=item Applying %s to %s will act on scalar(%s)
-(W misc) The pattern match (//), substitution (s///), and
-transliteration (tr///) operators work on scalar values. If you apply
+(W misc) The pattern match (C<//>), substitution (C<s///>), and
+transliteration (C<tr///>) operators work on scalar values. If you apply
one of them to an array or a hash, it will convert the array or hash to
a scalar value -- the length of an array, or the population info of a
hash -- and then work on that scalar value. This is probably not what

-(F) When vec is called in an lvalue context, the second argument must be
+(F) When C<vec> is called in an lvalue context, the second argument must be
greater than or equal to zero.

-(F) You've used the /e switch to evaluate the replacement for a
+(F) You've used the C</e> switch to evaluate the replacement for a
substitution, but perl found a syntax error in the code to evaluate,
most likely an unexpected right brace '}'.
If you actually want to pack Unicode codepoints, use the C<"U"> format
instead.
-=item chmod() mode argument is missing initial 0
-
-(W chmod) A novice will sometimes say
-
- chmod 777, $filename
-
-not realizing that 777 will be interpreted as a decimal number,
-equivalent to 01411. Octal constants are introduced with a leading 0 in
-Perl, as in C.

=item close() on unopened filehandle %s
(W unopened) You tried to close a filehandle that was never opened.
(F) Your Perl was compiled with B<-D>SETUID_SCRIPTS_ARE_SECURE_NOW, but
a version of the setuid emulator somehow got run anyway.
-=item sv_realpath: %s
-
-(S) You probably used some form of getcwd. The implementation of
-that functionality detected something odd in your filesystem
-environment and gave up (returning undef).
-
=item Switch (?(condition)... contains too many branches in regex;
marked by <-- HERE in m/%s/
%NAME or C<%{EXPR}>. No implicit dereferencing is allowed--use the
{EXPR} forms as an explicit dereference. See L<perlref>.
-=item umask: argument is missing initial 0
-
-(W umask) A umask of 222 is incorrect. It should be 0222, because octal
-literals always start with 0 in Perl, as in C.
-
=item umask not implemented
(F) Your machine doesn't implement the umask function and you tried to
you should remove AutoLoader from @ISA and change C<use AutoLoader;> to
C<use AutoLoader 'AUTOLOAD';>.
+=item Use of "package" with no arguments is deprecated
+
+(D deprecated) You used the C<package> keyword without specifying a package
+name. So no namespace is current at all. Using this can cause many
+otherwise reasonable constructs to fail in baffling ways. C<use strict;>
+instead.

(F) You attempted to use a feature of printf that is accessible from
=item Using a hash as a reference is deprecated
-(D deprecated) You tried to use a hash as a reference, as in C<%foo->{"bar"}>
