Maciej, I could say I'm being stingy about CPU cycles since the program will be running continuously, but mostly "just because I can", or in this case can't. I think translation is pretty cool, and I've been trying to see what different things I can apply it to.
What do you mean by "Python is a meta-programming language for RPython"?
