This comes up with some regularity here. Go super search and enlighten yourself. And, to forestall the inevitable cascade of replies, the answers generally are:

1. Heretic!
2. Use Acme::Bleach
3. There's perl2exe
   perl2exe isn't secure you ignorant wanker!
   yes it is
   No it isn't
   Well, that's not what it's for anyway
4. B::Deparse will defeat any attempt at hiding source!

Short answer is no, it won't really work. Someone'll see the source, so throw a nasty license on it and hope for the best.
