I typically use POD like this:
=for comment
#your commented code goes here
=cut
A little explanation. The "=for x" directive says that only a processor that's formatting for the x output type should heed what's in the following block. For instance, you could say "=for html" and then put some html markup in the block and it should be rendered only by programs seeking to render html. The nice thing about "=for comment" is that no one will be outputting a "comment" format...:-).

Feel the white light, the light within
Be your own disciple, fan the sparks of will
For all of us waiting, your kingdom will come
