 A slice accesses several elements of a list, an array, or a hash
 simultaneously using a list of subscripts.  It's more convenient
 than writing out the individual elements as a list of separate
 scalar values.

+After all, I just told you that you need an array of references, so by

+
+Unfortunately, while this is true, it's still broken.  All the references
+in @AoA refer to the I<very same place>, and they will therefore all hold
+whatever was last in @array!  It's similar to the problem demonstrated in
+the following C program:
+
+    #include <pwd.h>
+    main() {
+	struct passwd *getpwnam(), *rp, *dp;
+	rp = getpwnam("root");

+		dp->pw_name, rp->pw_name);
+    }
+
+Which will print
+
+    daemon name is daemon
+    root name is daemon
+
+The problem is that both C<rp> and C<dp> are pointers to the same location
+in memory!  In C, you'd have to remember to malloc() yourself some new
+memory.  In Perl, you'll want to use the array constructor C<[]> or the
+hash constructor C<{}> instead.   Here's the right way to do the preceding

+

+	@array = somefunc($i);

 =head1 IDENTIFYING CHARACTER CODE SETS
@@ -588,44 +506,44 @@ To determine the character set you are running under from perl one
 could use the return value of ord() or chr() to test one or more 
 character values.  For example:
 
-    my $is_ascii  = "A" eq chr(65);
-    my $is_ebcdic = "A" eq chr(193);
+    $is_ascii  = "A" eq chr(65);
+    $is_ebcdic = "A" eq chr(193);
 
 Also, "\t" is a C<HORIZONTAL TABULATION> character so that:
 
-    my $is_ascii  = ord("\t") == 9;
-    my $is_ebcdic = ord("\t") == 5;
+    $is_ascii  = ord("\t") == 9;
+    $is_ebcdic = ord("\t") == 5;
 
 To distinguish EBCDIC code pages try looking at one or more of
 the characters that differ between them.  For example:
 
-    my $is_ebcdic_37   = "\n" eq chr(37);
-    my $is_ebcdic_1047 = "\n" eq chr(21);
+    $is_ebcdic_37   = "\n" eq chr(37);
+    $is_ebcdic_1047 = "\n" eq chr(21);
 
 Or better still choose a character that is uniquely encoded in any
 of the code sets, e.g.:
 
-    my $is_ascii           = ord('[') == 91;
-    my $is_ebcdic_37       = ord('[') == 186;
-    my $is_ebcdic_1047     = ord('[') == 173;
-    my $is_ebcdic_POSIX_BC = ord('[') == 187;
+    $is_ascii           = ord('[') == 91;
+    $is_ebcdic_37       = ord('[') == 186;
+    $is_ebcdic_1047     = ord('[') == 173;
+    $is_ebcdic_POSIX_BC = ord('[') == 187;
 
 However, it would be unwise to write tests such as:
 
-    my $is_ascii = "\r" ne chr(13);  #  WRONG
-    my $is_ascii = "\n" ne chr(10);  #  ILL ADVISED
+    $is_ascii = "\r" ne chr(13);  #  WRONG
+    $is_ascii = "\n" ne chr(10);  #  ILL ADVISED
 
 Obviously the first of these will fail to distinguish most ASCII machines
-from either a CCSID 0037, a 1047, or a POSIX-BC EBCDIC machine since "\r" eq
