You mean like C<unless caller> ? (Try it.)

Hopefully this issue becomes too trivial to mention,
by virtue of Perl being parsable by things other than perl,
and by the introduction of a powerful, highly integrated
preprocessor. I like POD, but it needs to be evolved to
the point where it's not just about POD any more.
