way. See L<perlfunc/unpack>.

(W) You've run afoul of the rule that says that any list operator followed
instead of Perl. Check the #! line, or manually feed your script
into Perl yourself.

+(W) This prefix usually indicates that a DESTROY() method raised

+number of times, the warning is issued only once for any number
+of failures that would otherwise result in the same message being

you thought. Normally it's pretty easy to disambiguate it by supplying
a missing quote, operator, parenthesis pair or declaration.
+=item Ambiguous call resolved as CORE::%s(), qualify as such or use &
+
+(W) A subroutine you have declared has the same name as a Perl keyword,
+and you have used the name without qualification for calling one or the
+other. Perl decided to call the builtin because the subroutine is
+not imported.
+
+To force interpretation as a subroutine call, either put an ampersand
+before the subroutine name, or qualify the name with its package.
+Alternatively, you can import the subroutine (or pretend that it's
+imported with the C<use subs> pragma).
+
+To silently interpret it as the Perl operator, use the C<CORE::> prefix
+on the operator (e.g. C<CORE::log($x)>) or by declaring the subroutine

Something like this will reproduce the error:

=item Can't locate auto/%s.al in @INC
(F) A function (or method) was called in a package which allows autoload,
of upgradability. Upgrading to undef indicates an error in the
code calling sv_upgrade.

+=item Complex regular subexpression recursion limit (%d) exceeded
+
+(W) The regular expression engine uses recursion in complex situations
+where back-tracking is required. Recursion depth is limited to 32766,
+or perhaps less in architectures where the stack cannot grow
+arbitrarily. ("Simple" and "medium" situations are handled without
+recursion and are not subject to a limit.) Try shortening the string
+under examination; looping in Perl code (e.g. with C<while>) rather

(W) You tried to do a connect on a closed socket. Did you forget to check
the return value of your socket() call? See L<perlfunc/connect>.

+
+(F) A constant value (perhaps declared using the C<use constant> pragma)

+indicates a syntax error in dereferencing the constant value.

+
+=item %s: Eval-group not allowed, use re 'eval'

+(F) A regular expression contained the C<(?{ ... })> zero-width assertion,
+but that construct is only allowed when the C<use re 'eval'> pragma is
+in effect. See L<perlre/(?{ code })>.
+
+=item %s: Eval-group not allowed at run time
+
+(F) Perl tried to compile a regular expression containing the C<(?{ ... })>
+zero-width assertion at run time, as it would when the pattern contains
+interpolated values. Since that is a security risk, it is not allowed.
+If you insist, you may still do this by explicitly building the pattern
+from an interpolated string at run time and using that in an eval().
+See L<perlre/(?{ code })>.

a return, a goto, or a loop control statement.

+(W) You are blessing a reference to a zero length string. This has

the request was judged large enough (compile-time default is 64K), so
a possibility to shut down by trapping this error is granted.

+(W) You gave a single reference where Perl was expecting a list with

-=item Use of "$$<digit>" to mean "${$}<digit>" is deprecated
-
-(D) Perl versions before 5.004 misinterpreted any type marker followed
-by "$" and a digit. For example, "$$0" was incorrectly taken to mean
-"${$}0" instead of "${$0}". This bug is (mostly) fixed in Perl 5.004.
-
-However, the developers of Perl 5.004 could not fix this bug completely,
-because at least two widely-used modules depend on the old meaning of

(D) This was an ill-advised attempt to emulate a poorly defined B<awk> feature.
(D) As an (ahem) accidental feature, C<AUTOLOAD> subroutines are looked

+=item Use of reserved word "%s" is deprecated

+(D) The indicated bareword is a reserved word. Future versions of perl
