=item Bad arg length for %s, is %d, should be %d
situation typically indicates that the parent program under which Perl
may be running (e.g. cron) is being very careless.
+=item Can't kill a non-numeric process ID
+
+(F) Process identifiers must be (signed) integers. It is a fatal error to
+attempt to kill() an undefined, empty-string or otherwise non-numeric
+process identifier.
+
=item Can't "last" outside a loop block
(F) A "last" statement was executed to break out of the current block,
For example you cannot force little-endianness on a type that
is inside a big-endian group.
+=item Can't use keyword '%s' as a label
+
+(F) You attempted to use a reserved keyword, such as C<print> or C<BEGIN>,
+as a statement label. This is disallowed since Perl 5.11.0.

=item Can't use "my %s" in sort comparison
(F) The global variables $a and $b are reserved for sort comparisons.
=item $* is no longer supported
(S deprecated, syntax) The special variable C<$*>, deprecated in older perls, has
-been removed as of 5.9.0 and is no longer supported. You should use the
-C<//m> and C<//s> regexp modifiers instead.
+been removed as of 5.9.0 and is no longer supported. In previous versions of perl the use of
+C<$*> enabled or disabled multi-line matching within a string.
+
+Instead of using C<$*> you should use the C</m> (and maybe C</s>) regexp
+modifiers. (In older versions: when C<$*> was set to a true value then all regular
+expressions behaved as if they were written using C</m>.)
=item $# is no longer supported
(F) An ancient error message that almost nobody ever runs into anymore.
But before sort was a keyword, people sometimes used it as a filehandle.
-=item Sort subroutine didn't return a numeric value
-
-(F) A sort comparison routine must return a number. You probably blew
-it by not using C<< <=> >> or C<cmp>, or by not using them correctly.
-See L<perlfunc/sort>.

=item Sort subroutine didn't return single value
(F) A sort comparison subroutine may not return a list value with more
=item Too late for "-%s" option
(X) The #! line (or local equivalent) in a Perl script contains the
-B<-M>, B<-m> or B<-C> option. This is an error because those options
-are not intended for use inside scripts. Use the C<use> pragma instead.

+
+In the case of B<-M> and B<-m>, this is an error because those options are
+not intended for use inside scripts. Use the C<use> pragma instead.
+
+The B<-C> option only works if it is specified on the command line as well
+(with the same sequence of letters or numbers following). Either specify
+this option on the command line, or, if your system supports it, make your
+script executable and run it directly instead of passing it to perl.

repeatedly, the C</g> has no effect.
-=item Use of implicit split to @_ is deprecated
-
-(D deprecated, W syntax) It makes a lot of work for the compiler when you
-clobber a subroutine's argument list, so it's better if you assign the results
-of a split() explicitly to an array (or list).
