Fijal, I'm not sure you even understand my perspective. None of your comments in response have given me confidence that you do. I have no disagreement with you about how far "PyPy could go". Obviously, we could re-create the entire Python ecosystem including the scientific stack under its run-time. I just question your understanding of how expensive and time-consuming that would be. My official position is that I thi…

From having read the various replies to this and similar threads, I think a basic problem (as Travis pointed out) is that Fijal has been (1) highly dismissive of numpy and particularly cython, which a lot of really smart people have put a lot of time and effort into and created an amazing scientific community within python, and (2) confrontational with people who are trying to lend an alternative opinion which has be…

My thoughts exactly.

I like pypy and its ambitions, last time I tested it, about a month ago it was very speedy and startup time considerable faster than Cpython. However the regex exercises I wanted to do couldnt be done. Pypy seemingly didnt have a good regexp engine. If I remember correctly, something with groups and backwards-reference... Has that changed?

Hi, could you give some details about those regexes that you were trying to run? Are you sure these are problems with the PyPy implementation, not with the Python regexp spec itself? I've used grouping and back-references with pypy with no problems so far, so I wonder which case you're talking about.

Yes I am sure it was the pypy implementation since the same regex would do fine on python2.7.

Unfortunately I dont have the regex at hand, just remembering it was something with groups and backtracking.
