Log Message:
-----------
add a new warning against using \ in qw()
I've seen AI-generated code try to use qw() to create lists containing
strings with embedded whitespace using qw and \ to "protect" the
whitespace. Things like:
my @list = qw(
foo
bar\ baz
);
Just like occurences of ',' and '#', I believe this should warn.
Note that the warning will only be emitted when the \ is followed by
actual whitespace, so code like the following (from lib/App/Cpan.pm)
will not warn:
my $epic_fail_words = join '|',
qw( Error stop(?:ping)? problems force not unsupported
fail(?:ed)? Cannot\s+install );
