functioning as a class, but that package doesn't define that particular
method, nor does any of its base classes. See L<perlobj>.
+=item Can't locate PerlIO%s
+
+(F) You tried to use in open() a PerlIO layer that does not exist,
+e.g. open(FH, ">:nosuchlayer", "somefile").
+
=item (perhaps you forgot to load "%s"?)
(F) This is an educated guess made in conjunction with the message
that it is simpler or backtracks less. (See L<perlfaq2> for information
on I<Mastering Regular Expressions>.)
+=item cond_broadcast() called on unlocked variable
+
+(W threads) Within a thread-enabled program, you tried to call
+cond_broadcast() on a variable which wasn't locked. The cond_broadcast()
+function is used to wake up another thread that is waiting in a
+cond_wait(). To ensure that the signal isn't sent before the other thread
+has a chance to enter the wait, it is usual for the signaling thread to
+first wait for a lock on variable. This lock attempt will only succeed
+after the other thread has entered cond_wait() and thus relinquished the
+lock.
+
+
+=item cond_signal() called on unlocked variable
+
+(W threads) Within a thread-enabled program, you tried to call
+cond_signal() on a variable which wasn't locked. The cond_signal()
+function is used to wake up another thread that is waiting in a
+cond_wait(). To ensure that the signal isn't sent before the other thread
+has a chance to enter the wait, it is usual for the signaling thread to
+first wait for a lock on variable. This lock attempt will only succeed
+after the other thread has entered cond_wait() and thus relinquished the

=item connect() on closed socket %s
(W closed) You tried to do a connect on a closed socket. Did you forget
=item Constant subroutine %s redefined
-(S|W redefine) You redefined a subroutine which had previously been
+(S) You redefined a subroutine which had previously been
eligible for inlining. See L<perlsub/"Constant Functions"> for
commentary and workarounds.
=item Exiting format via %s
-(W exiting) You are exiting an eval by unconventional means, such as a
+(W exiting) You are exiting a format by unconventional means, such as a
goto, or a loop control statement.
=item Exiting pseudo-block via %s
=item perlio: argument list not closed for layer "%s"
-(S) When pushing a layer with arguments onto the Perl I/O system you forgot
-the ) that closes the argument list. (Layers take care of transforming
+(W layer) When pushing a layer with arguments onto the Perl I/O system you
+forgot the ) that closes the argument list. (Layers take care of transforming
data between external and internal representations.) Perl stopped parsing
the layer list at this point and did not attempt to push this layer.
If your program didn't explicitly request the failing operation, it may be
the result of the value of the environment variable PERLIO.
-=item perlio: invalid separator character %s in attribute list
+=item perlio: invalid separator character %s in layer specification list %s
-(S) When pushing layers onto the Perl I/O system, something other than a
+(W layer) When pushing layers onto the Perl I/O system, something other than a
colon or whitespace was seen between the elements of a layer list.
If the previous attribute had a parenthesised parameter list, perhaps that
list was terminated too soon.
=item perlio: unknown layer "%s"
-(S) An attempt was made to push an unknown layer onto the Perl I/O
+(W layer) An attempt was made to push an unknown layer onto the Perl I/O
system. (Layers take care of transforming data between external and
internal representations.) Note that some layers, such as C<mmap>,
are not supported in all environments. If your program didn't
target of the change to
%ENV which produced the warning.
+=item thread failed to start: %s
+
+(F) The entry point function of threads->create() failed for some reason.

=item times not implemented
(F) Your version of the C library apparently doesn't do times(). I
