+NAME
+ MRO::Compat - mro::* interface compatibility for Perls < 5.9.5
+
+SYNOPSIS
+ package PPP; use base qw/Exporter/;
+ package X; use base qw/PPP/;
+ package Y; use base qw/PPP/;
+ package Z; use base qw/PPP/;
+
+ package FooClass; use base qw/X Y Z/;
+
+ package main;
+ use MRO::Compat;
+ my $linear = mro::get_linear_isa('FooClass');
+ print join(q{, }, @$linear);
+
+ # Prints: FooClass, X, PPP, Exporter, Y, Z
+
+DESCRIPTION
+ The "mro" namespace provides several utilities for dealing with method
+ resolution order and method caching in general in Perl 5.9.5 and higher.
+
+ This module provides those interfaces for earlier versions of Perl (back
+ to 5.6.0 anyways).
+
+ It is a harmless no-op to use this module on 5.9.5+. That is to say,
+ code which properly uses MRO::Compat will work unmodified on both older
+ Perls and 5.9.5+.
+
+ If you're writing a piece of software that would like to use the parts
+ of 5.9.5+'s mro:: interfaces that are supported here, and you want
+ compatibility with older Perls, this is the module for you.
+
+ Some parts of this code will work better and/or faster with
+ Class::C3::XS installed (which is an optional prereq of Class::C3, which
+ is in turn a prereq of this package), but it's not a requirement.
+
+ This module never exports any functions. All calls must be fully
+ qualified with the "mro::" prefix.
+
+ The interface documentation here serves only as a quick reference of
+ what the function basically does, and what differences between
+ MRO::Compat and 5.9.5+ one should look out for. The main docs in 5.9.5's
+ mro are the real interface docs, and contain a lot of other useful
+ information.
+
+Functions
+ mro::get_linear_isa($classname[, $type])
+ Returns an arrayref which is the linearized "ISA" of the given class.
+ Uses whichever MRO is currently in effect for that class by default, or
+ the given MRO (either "c3" or "dfs" if specified as $type).
+
+ The linearized ISA of a class is a single ordered list of all of the
+ classes that would be visited in the process of resolving a method on
+ the given class, starting with itself. It does not include any duplicate
+ entries.
+
+ Note that "UNIVERSAL" (and any members of "UNIVERSAL"'s MRO) are not
+ part of the MRO of a class, even though all classes implicitly inherit
+ methods from "UNIVERSAL" and its parents.
+
+ mro::import
+ This allows the "use mro 'dfs'" and "use mro 'c3'" syntaxes, providing
+ you "use MRO::Compat" first. Please see the "USING C3" section for
+ additional details.
+
+ mro::set_mro($classname, $type)
+ Sets the mro of $classname to one of the types "dfs" or "c3". Please see
+ the "USING C3" section for additional details.
+
+ mro::get_mro($classname)
+ Returns the MRO of the given class (either "c3" or "dfs").
+
+ It considers any Class::C3-using class to have C3 MRO even before
+ Class::C3::initialize() is called.
+
+ mro::get_isarev($classname)
+ Returns an arrayref of classes who are subclasses of the given
+ classname. In other words, classes in whose @ISA hierarchy we appear, no
+ matter how indirectly.
+
+ This is much slower on pre-5.9.5 Perls with MRO::Compat than it is on
+ 5.9.5+, as it has to search the entire package namespace.
+
+ mro::is_universal($classname)
+ Returns a boolean status indicating whether or not the given classname
+ is either "UNIVERSAL" itself, or one of "UNIVERSAL"'s parents by @ISA
+ inheritance.
+
+ Any class for which this function returns true is "universal" in the
+ sense that all classes potentially inherit methods from it.
+
+ mro::invalidate_all_method_caches
+ Increments "PL_sub_generation", which invalidates method caching in all
+ packages.
+
+ Please note that this is rarely necessary, unless you are dealing with a
+ situation which is known to confuse Perl's method caching.
+
+ mro::method_changed_in($classname)
+ Invalidates the method cache of any classes dependent on the given
+ class. In MRO::Compat on pre-5.9.5 Perls, this is an alias for
+ "mro::invalidate_all_method_caches" above, as pre-5.9.5 Perls have no
+ other way to do this. It will still enforce the requirement that you
+ pass it a classname, for compatibility.
+
+ Please note that this is rarely necessary, unless you are dealing with a
+ situation which is known to confuse Perl's method caching.
+
+ mro::get_pkg_gen($classname)
+ Returns an integer which is incremented every time a local method of or
+ the @ISA of the given package changes on Perl 5.9.5+. On earlier Perls
+ with this MRO::Compat module, it will probably increment a lot more
+ often than necessary.
+
+USING C3
+ While this module makes the 5.9.5+ syntaxes "use mro 'c3'" and
+ "mro::set_mro("Foo", 'c3')" available on older Perls, it does so merely
+ by passing off the work to Class::C3.
+
+ It does not remove the need for you to call "Class::C3::initialize()",
+ "Class::C3::reinitialize()", and/or "Class::C3::uninitialize()" at the
+ appropriate times as documented in the Class::C3 docs. These three
+ functions are always provided by MRO::Compat, either via Class::C3
+ itself on older Perls, or directly as no-ops on 5.9.5+.

+
+MRO::Compat - mro::* interface compatibility for Perls < 5.9.5
+
+=head1 SYNOPSIS
+
+ package PPP; use base qw/Exporter/;
+ package X; use base qw/PPP/;
+ package Y; use base qw/PPP/;
+ package Z; use base qw/PPP/;
+
+ package FooClass; use base qw/X Y Z/;
+
+ package main;

+ my $linear = mro::get_linear_isa('FooClass');
+ print join(q{, }, @$linear);
+
+ # Prints: FooClass, X, PPP, Exporter, Y, Z
+
+=head1 DESCRIPTION
+
+The "mro" namespace provides several utilities for dealing
+with method resolution order and method caching in general
+in Perl 5.9.5 and higher.
+
+This module provides those interfaces for
+earlier versions of Perl (back to 5.6.0 anyways).
+
+It is a harmless no-op to use this module on 5.9.5+. That
+is to say, code which properly uses L<MRO::Compat> will work
+unmodified on both older Perls and 5.9.5+.
+
+If you're writing a piece of software that would like to use
+the parts of 5.9.5+'s mro:: interfaces that are supported
+here, and you want compatibility with older Perls, this
+is the module for you.
+
+Some parts of this code will work better and/or faster with
+L<Class::C3::XS> installed (which is an optional prereq
+of L<Class::C3>, which is in turn a prereq of this
+package), but it's not a requirement.
+
+This module never exports any functions. All calls must
+be fully qualified with the C<mro::> prefix.
+
+The interface documentation here serves only as a quick
+reference of what the function basically does, and what
+differences between L<MRO::Compat> and 5.9.5+ one should
+look out for. The main docs in 5.9.5's L<mro> are the real
+interface docs, and contain a lot of other useful information.
+
+=head1 Functions
+
+=head2 mro::get_linear_isa($classname[, $type])
+
+Returns an arrayref which is the linearized "ISA" of the given class.
+Uses whichever MRO is currently in effect for that class by default,
+or the given MRO (either C<c3> or C<dfs> if specified as C<$type>).
+
+The linearized ISA of a class is a single ordered list of all of the
+classes that would be visited in the process of resolving a method
+on the given class, starting with itself. It does not include any
+duplicate entries.
+
+Note that C<UNIVERSAL> (and any members of C<UNIVERSAL>'s MRO) are not
+part of the MRO of a class, even though all classes implicitly inherit
+methods from C<UNIVERSAL> and its parents.

+}
+
+=head2 mro::import
+
+This allows the C<use mro 'dfs'> and
+C<use mro 'c3'> syntaxes, providing you
+L<use MRO::Compat> first. Please see the
+L</USING C3> section for additional details.

+Sets the mro of C<$classname> to one of the types

+
+ return;
+}
+
+=head2 mro::get_mro($classname)
+
+Returns the MRO of the given class (either C<c3> or C<dfs>).
+
+It considers any Class::C3-using class to have C3 MRO
+even before L<Class::C3::initialize()> is called.

+=head2 mro::get_isarev($classname)
+
+Returns an arrayref of classes who are subclasses of the
+given classname. In other words, classes in whose @ISA
+hierarchy we appear, no matter how indirectly.
+
+This is much slower on pre-5.9.5 Perls with MRO::Compat
+than it is on 5.9.5+, as it has to search the entire

+=head2 mro::is_universal($classname)
+
+Returns a boolean status indicating whether or not
+the given classname is either C<UNIVERSAL> itself,
+or one of C<UNIVERSAL>'s parents by C<@ISA> inheritance.
+
+Any class for which this function returns true is
+"universal" in the sense that all classes potentially

+
+=head2 mro::invalidate_all_method_caches
+
+Increments C<PL_sub_generation>, which invalidates method
+caching in all packages.
+
+Please note that this is rarely necessary, unless you are
+dealing with a situation which is known to confuse Perl's
+method caching.

+
+=head2 mro::method_changed_in($classname)
+
+Invalidates the method cache of any classes dependent on the
+given class. In L<MRO::Compat> on pre-5.9.5 Perls, this is
+an alias for C<mro::invalidate_all_method_caches> above, as
+pre-5.9.5 Perls have no other way to do this. It will still
+enforce the requirement that you pass it a classname, for
+compatibility.

+
+=head2 mro::get_pkg_gen($classname)
+
+Returns an integer which is incremented every time a local
+method of or the C<@ISA> of the given package changes on
+Perl 5.9.5+. On earlier Perls with this L<MRO::Compat> module,
+it will probably increment a lot more often than necessary.

+=head1 USING C3
+
+While this module makes the 5.9.5+ syntaxes
+C<use mro 'c3'> and C<mro::set_mro("Foo", 'c3')> available
+on older Perls, it does so merely by passing off the work
+to L<Class::C3>.
+
+It does not remove the need for you to call
+C<Class::C3::initialize()>, C<Class::C3::reinitialize()>, and/or
+C<Class::C3::uninitialize()> at the appropriate times
+as documented in the L<Class::C3> docs. These three functions
+are always provided by L<MRO::Compat>, either via L<Class::C3>
+itself on older Perls, or directly as no-ops on 5.9.5+.
