mgorny: hm, I'm not really able to judge that patch. it looks reasonable, but who knows whether it breaks some weird platform :-(. should we put it into a branch and run buildbots and try to see?
cfbolz: i don't think it can break anything, as it only changes the case that currently thrown an AssertionError
(i've only refactored everything else to make it use less indent)
Is there some command line option to make PyPy faster? Or does it already have any possible optimization enabled?
I was peeking at the --jit option and saw this vec=N option, but using --jit vec=1 didn't seem to improve things (it either didn't do anything useful for this specific script, or I'm using it wrong)
I also read this thing about "stackless python" allowing "massively concurrent style"... but I don't know if that directly changes the way to run a program, or if you have to rewrite the program to leverage it
