(F) msgsnd() requires a string at least as long as sizeof(long).
-=item %s argument is not a HASH or ARRAY element
+=item %s argument is not a HASH or ARRAY element or a subroutine
(F) The argument to exists() must be a hash or array element or a
subroutine with an ampersand, such as:
(W syntax) The @ISA array contained the name of another package that
doesn't seem to exist.
-=item Can't locate package %s for the parents of %s
-
-(W syntax) You did not define (or require/use) the first package,
-which is named as a (possibly indirect) parent of the second by
-C<@ISA> inheritance. Perl will treat this as if the undefined
-package had an empty C<@ISA>.
-
=item Can't locate PerlIO%s
(F) You tried to use in open() a PerlIO layer that does not exist,
(F) There is currently a limit on the length of string which lookbehind can
handle. This restriction may be eased in a future release.
+=item Lost precision when %s %f by 1
+
+(W) The value you attempted to increment or decrement by one is too large
+for the underlying floating point representation to store accurately,
+hence the target of C<++> or C<--> is unchanged. Perl issues this warning
+because it has already switched from integers to floating point when values
+are too large for integers, and now even floating point is insufficient.
+You may wish to switch to using L<Math::BigInt> explicitly.
+
=item lstat() on filehandle %s
(W io) You tried to do an lstat on a filehandle. What did you mean
(P) scan_num() got called on something that wasn't a number.
+=item panic: sv_chop %s
+
+(P) The sv_chop() routine was passed a position that is not within the
+scalar's string buffer.
+
=item panic: sv_insert
(P) The sv_insert() routine was told to remove more string than there
(F) The unpack format P must have an explicit size, not "*".
-=item B<-P> not allowed for setuid/setgid script
-
-(F) The script would have to be opened by the C preprocessor by name,
-which provides a race condition that breaks security.
-
=item POSIX class [:%s:] unknown in regex; marked by <-- HERE in m/%s/
(F) The class in the character class [: :] syntax is unknown. The <-- HERE
literal @foo, then write it as \@foo; otherwise find out what happened
to the array you apparently lost track of.
+=item Possible unintended interpolation of $\ in regex
+
+(W ambiguous) You said something like C<m/$\/> in a regex.
+The regex C<m/foo$\s+bar/m> translates to: match the word 'foo', the output
+record separartor (see L<perlvar/$\>) and the letter 's' (one time or more)
+followed by the word 'bar'.
+
+If this is what you intended then you can silence the warning by using
+C<m/${\}/> (for example: C<m/foo${\}s+bar/>).
+
+If instead you intended to match the word 'foo' at the end of the line
+followed by whitespace and the word 'bar' on the next line then you can use
+C<m/$(?)\/> (for example: C<m/foo$(?)\s+bar/>).
+
=item pragma "attrs" is deprecated, use "sub NAME : ATTRS" instead
(D deprecated) You have written something like this:
L<perlipc/"Signals">. See also "Process terminated by SIGTERM/SIGINT"
in L<perlos2>.
+=item Prototype after '%c' for %s : %s
+
+(W syntax) A character follows % or @ in a prototype. This is useless,
+since % and @ gobble the rest of the subroutine arguments.
+
=item Prototype mismatch: %s vs %s
(S prototype) The subroutine being declared or defined had previously been
(W misc) The version string contains invalid characters at the end, which
are being ignored.
-=item v-string in use/require is non-portable
-
-(W portable) The use of v-strings is non-portable to older, pre-5.6, Perls.
-If you want your scripts to be backward portable, use the floating
-point version number: for example, instead of C<use 5.6.1> say
-C<use 5.006_001>. This of course won't make older Perls suddenly start
-understanding newer features, but at least they will show a sensible
-error message indicating the required minimum version.
-
-This warning is suppressed if the C<use 5.x.y> is preceded by a
-C<use 5.006> (see C<use VERSION> in L<perlfunc/use>).
-
=item Warning: something's wrong
(W) You passed warn() an empty string (the equivalent of C<warn "">) or
