One issue I would be concerned with is why you have non-PERL coders looking at PERL code. As a test tools developer for a major corporation, we have allowed our users to write "privates" for their own testing needs. We also provided an English-like scripting language (gotta love eval!!) for them to automate most of their activities. Because of this, we have maybe 3 or 4 users who actually bother trying to write their own privates and the rest simply use the provided scripting language.

I guess what I'm saying is that if you treat PERL as a scripting language that anyone with half a brain should be able to read without a problem (like BASIC), then you're going to run into problems. If you treat it as a full-fledged programming language that happens to be interpreted and not compiled, then your users will treat it with the appropriate respect. A given user wouldn't try and read your C, FORTRAN, or COBOL code, would they?
