There is another consideration for methods that are created via AUTOLOAD.

I saw an article somewhere about (possibly user.perl.org or slashdot.org or an article some where on the O'Reilly sites) where someone was suggesting using tests as a way for determining what methods exist in dynamic language code, it wasn't Perl specific. When I read the article someone had responded that they had created a demo of the method using vim which may be of some help.
