+(W misc) The pattern match (C<//>), substitution (C<s///>), and
+transliteration (C<tr///>) operators work on scalar values. If you apply
one of them to an array or a hash, it will convert the array or hash to
a scalar value -- the length of an array, or the population info of a
hash -- and then work on that scalar value. This is probably not what

greater than or equal to zero.

substitution, but perl found a syntax error in the code to evaluate,
most likely an unexpected right brace '}'.
If you actually want to pack Unicode codepoints, use the C<"U"> format
instead.

-
-(W chmod) A novice will sometimes say

- chmod 777, $filename

-not realizing that 777 will be interpreted as a decimal number,
-equivalent to 01411. Octal constants are introduced with a leading 0 in

(W unopened) You tried to close a filehandle that was never opened.

do. See L<perlfunc/require>.

=item (Did you mean &%s instead?)
(W) You probably referred to an imported subroutine &FOO as $FOO or some

=item Not a CODE reference
(F) Perl was trying to evaluate a reference to a code value (that is, a
%NAME or C<%{EXPR}>. No implicit dereferencing is allowed--use the
{EXPR} forms as an explicit dereference. See L<perlref>.

+(D deprecated) You used the C<package> keyword without specifying a package

-(D deprecated) You tried to use a hash as a reference, as in C<%foo->{"bar"}>
