What programming languages do you use?

Primarily? Java, Groovy, Python. And bash if you want to consider it a programming language.

That I dabble in, or use here and there for random "whatever"? Add C, C++, R, Octave, Prolog, and Common Lisp.

And then there's the "I want to learn this one day" list, which would A. take too long to type out, and B. bore everyone to tears anyway.
