Not really.

To be frank, with any language its impossible. It may be boring to point out, but any computer program eventually tells a CPU to do something, and that can always be intercepted and monitored. So the issue is not "Can we prevent people from reverse engineering our code" but rather "can we make it difficult enough for them to do that they probably won't try, and even if they do the most likely wont suceed, at least not for all of it". Can the later problem be addressed? Probably it can be made fairly difficult. Many people consider perl2exe and similar stuff to offer a signifigant advantage. You could probably contrive some mechanism using encryption and a morphed perl binary to make it somewhat difficult. Source filters might stop the idly curious. Etc.

Ultimately however if someone with physical access to a machine wants to know whats running on the machine they can always find out.
