It was my impression that the "current SpiderMonkey implementation is nothing to get excited about in terms of performance" which made your unfavourable comparison to CPython so puzzling (and does the tamarin website actually show any performance comparisons with CPython?) > My point is that there are optimizing hard-code compiler implementations > of many dynamic languages, including LISP, Self, and Smalltalk, but not > Python. I guess Lisp is a safe-ish example but I don't think Self really made it out of the lab, and it really depends which Smalltalk implementation you have in mind and what you think about Pysco. -- http://mail.python.org/mailman/listinfo/python-list
