-
-(P) The setegid() call failed for some reason in the setuid emulator of
-suidperl.
-
-=item Can't do seteuid!
-
-(P) The setuid emulator of suidperl failed for some reason.
-
-=item Can't do setuid
-
-(F) This typically means that ordinary perl tried to exec suidperl to do
-setuid emulation, but couldn't exec it. It looks for a name of the form
-sperl5.000 in the same directory that the perl executable resides under
-the name perl5.000, typically /usr/local/bin on Unix machines. If the
-file is there, check the execute permissions. If it isn't, ask your
-sysadmin why he and/or she removed it.

=item Can't do waitpid with flags
(F) This machine doesn't have either waitpid() or wait4(), so only
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,
(P) An error peculiar to VMS. Perl thought stdin was a pipe, and tried
to reopen it to accept binary data. Alas, it failed.
-=item Can't resolve method `%s' overloading `%s' in package `%s'
+=item Can't resolve method "%s" overloading "%s" in package "%s"
(F|P) Error resolving overloading specified by a method name (as opposed
to a subroutine reference): no such method callable via the package. If
method name is C<???>, this is an internal error.

you cannot use IO layers. To have PerlIO Perl must be configured

+Instead of using C<$*> you should use the C</m> (and maybe C</s>) regexp

(F) You tried to unpack something that didn't comply with UTF-8 encoding
rules and perl was unable to guess how to make more progress.

-(F) Perl aborted due to a too important number of signals pending. This
+(F) Perl aborted due to a too high number of signals pending. This
usually indicates that your operating system tried to deliver signals

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:

(S precedence) The old irregular construct

L<perlref>.
-=item Script is not setuid/setgid in suidperl
-
-(F) Oddly, the suidperl program was invoked on a script without a setuid
-or setgid bit set. This doesn't make much sense.
-
=item Search pattern not terminated
(F) The lexer couldn't find the final delimiter of a // or m{}
(W signal) The signal handler named in %SIG doesn't, in fact, exist.
Perhaps you put it into the wrong package?
+=item Smart matching a non-overloaded object breaks encapsulation

+(F) You should not use the C<~~> operator on an object that does not
+overload it: Perl refuses to use the object's underlying structure for
+the smart match.

(F) An ancient error message that almost nobody ever runs into anymore.

was either never opened or has since been closed.

(P) Overloading resolution over @ISA tree may be broken by importation
stubs. Stubs should never be implicitly created, but explicit calls to
substr is used in an lvalue context (as the left hand side of an
assignment or as a subroutine argument for example).

+B<-T> option (or the B<-t> option), but Perl was not invoked with B<-T> in its command line.
This is an error because, by the time Perl discovers a B<-T> in a
script, it's too late to properly taint everything from the environment.
So Perl gives up.
If the Perl script is being executed as a command using the #!
mechanism (or its local equivalent), this error can usually be fixed by
-editing the #! line so that the B<-T> option is a part of Perl's first
-argument: e.g. change C<perl -n -T> to C<perl -T -n>.

+argument: e.g. change C<perl -n -%c> to C<perl -%c -n>.
If the Perl script is being executed as C<perl scriptname>, then the

+The B<-C> option only works if it is specified on the command line as well

=item Use of bare << to mean <<"" is deprecated
(D deprecated, W syntax) You are now encouraged to use the explicitly quoted
