Usually I've found that when someone says "yes, I really need to do this" and doesn't provide an explanation, further digging often reveals that the person's problem has a much simpler and better solution than the proposed one.

So, I have to ask "why". Quite often, it turns out that a person's reasons for doing something, once explained, leads to different and better solutions for what they are trying to accomplish. Further, if you're just doing this to protect your intellectual work, you may wish to consider a programming language more suitable for that than Perl. In the Perl community, you are given a programming language and lots and lots of help for free. As a result, if you turn around and hide your source code, it's often frowned upon.

Also, Perl compilers are generally not terribly good. I don't know why your code is up to 20MB, but you should be aware that the entire Perl interpreter is embedded in the compiled version (which is required, due to the way Perl works).

So, if you explain why you want to do this, maybe we can help you find an easier solution.
