It takes a different approach to obfuscating code, but it sort of works.

I don't know if he was speaking of making the code you can see hard to

I like the advice given in the Perl FAQ "How can I hide the source for my Perl
program?", which says:

If you have to ask, you're not good enough to obfuscate or maintain your
