(F) List assignment to %ENV is not supported on some systems, notably VMS.
-=item Can't mkstemp() temporary file %s
-
-(F) The mkstemp() routine failed for some reason while trying to
-process a B<-e> switch. Maybe your temporary file partition
-is full, or over-protected, or clobbered.
-
-=item Can't mktemp() temporary file %s
-
-(F) The mktemp() routine failed for some reason while trying to
-process a B<-e> switch. Maybe your temporary file partition
-is full, or over-protected, or clobbered.

=item Can't modify %s in %s
(F) You aren't allowed to assign to the item indicated, or otherwise try to
an assignment operator, which implies modifying the value itself.
Perhaps you need to copy the value to a temporary, and repeat that.
+=item Cannot create temporary file "%s"
+
+(F) A temporary file could not created for some reason while trying to
+process a B<-e> switch. Maybe your temporary file partition is full,
+or over-protected, or clobbered.
+
=item Cannot find an opnumber for "%s"
(F) A string of a form C<CORE::word> was given to prototype(), but
there is no builtin with the name C<word>.
-=item Cannot open temporary file %s
+=item Cannot generate temporary filename
-(F) A temporary file could not created for some reason while trying to
-process a B<-e> switch. Maybe your temporary file partition is full,
-or over-protected, or clobbered.
+(F) While trying to process a B<-e> switch, a filename for a temporary
+file could not be generated. Maybe your temporary file partition is
+full, or over-protected, or clobbered.
=item Cannot resolve method `%s' overloading `%s' in package `%s'
Perl are likely to eliminate this arbitrary limitation. In the meantime,
try using scientific notation (e.g. "1e6" instead of "1_000_000").
-=item Odd number of elements in hash list
+=item Odd number of elements in hash assignment
-(S) You specified an odd number of elements to a hash list, which is odd,
-because hash lists come in key/value pairs.
+(S) You specified an odd number of elements to initialize a hash, which
+is odd, because hashes come in key/value pairs.
=item Offset outside string
(F) More than 100 levels of inheritance were used. Probably indicates
an unintended loop in your inheritance hierarchy.
+=item Reference found where even-sized list expected
+
+(W) You gave a single reference where Perl was expecting a list with
+an even number of elements (for assignment to a hash). This
+usually means that you used the anon hash constructor when you meant
+to use parens. In any case, a hash requires key/value B<pairs>.
+
+ %hash = { one => 1, two => 2, }; # WRONG
+ %hash = [ qw/ an anon array / ]; # WRONG
+ %hash = ( one => 1, two => 2, ); # right
+ %hash = qw( one 1 two 2 ); # also fine
+
=item Reference miscount in sv_replace()
(W) The internal sv_replace() function was handed a new SV with a
