You seem to want Acme::Bleach. The documentation and source code are short, but it works quite well at hiding your source code. You can even give your customer a printout of the source code and still have it protected.

    Interesting module and it works for small programs, I have to test it with larger programs, will there be any side effects because of this?.

      Well, Acme::Bleach rewrites the input file, so that will be a certain side effect. Other than that, you will have to find it out.
