(F) The script you specified can't be opened for the indicated reason.
-=item Can't provide tied hash usage; use keys(%hash) to test if empty
-
-(F) When a hash is evaluated in scalar context, bucket usage is
-returned if the hash is populated, and false is returned if the hash
-is empty. Bucket usage is not currently available for tied hashes.
-To test if a hash is empty or populated, use keys(%hash) in scalar
-context instead.

=item Can't read CRTL environ
(S) A warning peculiar to VMS. Perl tried to read an element of %ENV
long for Perl to handle. You have to be seriously twisted to write code
that triggers this error.
+=item DESTROY created new reference to dead object '%s'
+
+(F) A DESTROY() method created a new reference to the object which is
+just being DESTROYed. Perl is confused, and prefers to abort rather than
+to create a dangling reference.
+
=item Did not produce a valid header
See Server error.
=item (Do you need to predeclare %s?)
-(S) This is an educated guess made in conjunction with the message "%s
-found where operator expected". It often means a subroutine or module
+(S syntax) This is an educated guess made in conjunction with the message
+"%s found where operator expected". It often means a subroutine or module
name is being referenced that hasn't been declared yet. This may be
because of ordering problems in your file, or because of a missing
"sub", "package", "require", or "use" statement. If you're referencing
=item elseif should be elsif
-(S) There is no keyword "elseif" in Perl because Larry thinks it's ugly.
-Your code will be interpreted as an attempt to call a method named
+(S syntax) There is no keyword "elseif" in Perl because Larry thinks it's
+ugly. Your code will be interpreted as an attempt to call a method named
"elseif" for the class returned by the following block. This is
unlikely to be what you want.
(F) While under the C<use filetest> pragma, switching the real and
effective uids or gids failed.
+=item %ENV is aliased to %s
+
+(F) You're running under taint mode, and the C<%ENV> variable has been
+aliased to another hash, so it doesn't reflect anymore the state of the
+program's environment. This is potentially insecure.
+
=item Error converting file specification %s
(F) An error peculiar to VMS. Because Perl may have to deal with file
=item %s found where operator expected
-(S) The Perl lexer knows whether to expect a term or an operator. If it
-sees what it knows to be a term when it was expecting to see an
+(S syntax) The Perl lexer knows whether to expect a term or an operator.
+If it sees what it knows to be a term when it was expecting to see an
operator, it gives you this warning. Usually it indicates that an
operator or delimiter was omitted, such as a semicolon.
=item (Missing operator before %s?)
-(S) This is an educated guess made in conjunction with the message "%s
-found where operator expected". Often the missing operator is a comma.
+(S syntax) This is an educated guess made in conjunction with the message
+"%s found where operator expected". Often the missing operator is a comma.
=item Missing right brace on %s
=item (Missing semicolon on previous line?)
-(S) This is an educated guess made in conjunction with the message "%s
-found where operator expected". Don't automatically put a semicolon on
+(S syntax) This is an educated guess made in conjunction with the message
+"%s found where operator expected". Don't automatically put a semicolon on
the previous line just because you saw this message.
=item Modification of a read-only value attempted
(P) A "can't happen" error, because safemalloc() should have caught it
earlier.
+=item Repeated format line will never terminate (~~ and @# incompatible)
+
+(F) Your format containes the ~~ repeat-until-blank sequence and a
+numeric field that will never go blank so that the repetition never
+terminates. You might use ^# instead. See L<perlform>.
+
=item Reversed %s= operator
(W syntax) You wrote your assignment operator backwards. The = must
use the /g modifier. Currently, /c is meaningful only when /g is
used. (This may change in the future.)
-=item Use of freed value in iteration (perhaps you modified the iterated array within the loop?)
+=item Use of freed value in iteration
-(F) This is typically caused by code like the following:
+(F) Perhaps you modified the iterated array within the loop?
+This error is typically caused by code like the following:
@a = (3,4);
@a = () for (1,2,@a);
(W closure) During compilation, an inner named subroutine or eval is
attempting to capture an outer lexical that is not currently available.
