On: PyPy is faster than C, again: string formatting

I wouldn't say it's particularly targeted, let me show you the code that makes this happen: https://bitbucket.org/pypy/pypy/src/unroll-if-alt/pypy/objsp...

Yeah, the point is that by expressing the algorithm in Python, the JIT gets to go hog wild optimising tight loops like this one.

Which is great: why do all that work writing some kind of custom sprintf generating function when you can just let the JIT do it for you on the fly?
