Okay, Python's regular expressions lack the experimental features but they have everything else. There's no syntax for them, but you can write simple wrappers that will make their use very simple. I've written and published mine before, if you're interested I can repost the URL.
Python's standard library > CPAN for most cases, and for the rest there's Google.

That's a good feature. It prevents fucktards from writing unindented code, and prevents shit HTML copypastas from being used to copypasta shit unindented code. Have you actually used Python? At first, forced indentation looked weird to me (to say the least), but after using it for, like, 2 days, I realized it was the best idea ever. Not only you save lines and fit more useful lines on screen by sparing the }, but you know others are forced to write more proper code, which helps. I already indented code this way, so for me, it doesn't do anything (plus it saves me from using }); the real advantage is that others don't write shit.
