regards to the True/False constants. An expression like
``col.is_(True)`` will now render ``col IS true``
on the target platform, rather than converting the True/
False constant to an integer bound parameter.
This allows the ``is_()`` operator to work on MySQL when
given True/False constants.

labeled columns when apply_labels() is used; this mode
produces a SELECT where each column is labeled as in
<tablename>_<columnname>, to remove column name collisions
for a multiple table select. The fix is that if two labels
collide when combined with the table name, i.e.
"foo.bar_id" and "foo_bar.id", anonymous aliasing will be
applied to one of the dupes. This allows the ORM to handle
both columns independently; previously, 0.7
would in some cases silently emit a second SELECT for the
column that was "duped", and in 0.8 an ambiguous column error
would be emitted. The "keys" applied to the .c. collection
of the select() will also be deduped, so that the "column
being replaced" warning will no longer emit for any select()
that specifies use_labels, though the dupe key will be given
an anonymous label which isn't generally user-friendly.

- update "not supported" messages for empty inserts, mutlivalue inserts
- rework the ValuesBase approach for multiple value sets so that stmt.parameters
does store a list for multiple values; the _has_multiple_parameters flag now indicates
which of the two modes the statement is within. it now raises exceptions if a subsequent
call to values() attempts to call a ValuesBase with one mode in the style of the other
mode; that is, you can't switch a single- or multi- valued ValuesBase to the other mode,
and also if a multiple value is passed simultaneously with a kwargs set.
Added tests for these error conditions
- Calling values() multiple times in multivalue mode now extends the parameter list to
include the new parameter sets.
- add error/test if multiple *args were passed to ValuesBase.values()
- rework the compiler approach for multivalue inserts, back to where
_get_colparams() returns the same list of (column, value) as before, thereby
maintaining the identical number of append() and other calls when multivalue
is not enabled. In the case of multivalue, it makes a last-minute switch to return
a list of lists instead of the single list. As it constructs the additional lists, the inline
defaults and other calculated default parameters of the first parameter
set are copied into the newly generated lists so that these features continue
to function for a multivalue insert. Multivalue inserts now add no additional
function calls to the compilation for regular insert constructs.
- parameter lists for multivalue inserts now includes an integer index for all
parameter sets.
- add detailed documentation for ValuesBase.values(), including careful wording
to describe the difference between multiple values and an executemany() call.
- add a test for multivalue insert + returning - it works !
- remove the very old/never used "postgresql_returning"/"firebird_returning" flags.

Some databases support this syntax for inserts:
INSERT INTO table (id, name) VALUES
('v1', 'v2'),
('v3', 'v4');
which greatly increases INSERT speed.
It is now possible to pass a list of lists/tuples/dictionaries as
the values param to the Insert construct. We convert it to a flat
dictionary so we can continue using bind params. The above query
will be converted to:
INSERT INTO table (id, name) VALUES
(:id, :name),
(:id0, :name0);
Currently only supported on postgresql, mysql and sqlite.

[ticket:2592]
- [bug] Applying a column expression to a select
statement using a label with or without other
modifying constructs will no longer "target" that
expression to the underlying Column; this affects
ORM operations that rely upon Column targeting
in order to retrieve results. That is, a query
like query(User.id, User.id.label('foo')) will now
track the value of each "User.id" expression separately
instead of munging them together. It is not expected
that any users will be impacted by this; however,
a usage that uses select() in conjunction with
query.from_statement() and attempts to load fully
composed ORM entities may not function as expected
if the select() named Column objects with arbitrary
.label() names, as these will no longer target to
the Column objects mapped by that entity.

to help with generative building. Also slight adjustment
regarding how SS "correlates" columns; the new methodology
no longer applies meaning to the underlying
Table column being selected. This improves
some fairly esoteric situations, and the logic
that was there didn't seem to have any purpose.
- [feature] Some support for auto-rendering of a
relationship join condition based on the mapped
attribute, with usage of core SQL constructs.
E.g. select([SomeClass]).where(SomeClass.somerelationship)
would render SELECT from "someclass" and use the
primaryjoin of "somerelationship" as the WHERE
clause. This changes the previous meaning
of "SomeClass.somerelationship" when used in a
core SQL context; previously, it would "resolve"
to the parent selectable, which wasn't generally
useful. Related to [ticket:2245].
