I'm not convinced that having a language that's designed to obfuscate is actually all that much of an achievement.

I mean, putting together a programming language isn't all _that_ hard. The trick is in putting together one that is acutally useful. Perl fulfills that latter criteria, and at the same time, happens to have sufficient flexibility that it _can_ be obfuscated.

If you really want languages that are hard to decode, well, why not start at machine code. There's a reason it's not commonly used, after all.
