Hi Paolo, Just a quick note as an answer to your long and detailed e-mail (thanks for it, btw).
On the whole you're making quite some efforts to get Python fast, starting with a subset of Python and adding feature after feature until it is more or less complete, while benchmarking at every step. This is not a new approach: it has been tried before for Python. Usually, this kind of project ends up being not used and forgotten, because it's "only" 80% or 90% compatible but not 99% -- and people care much more, on average, about 99% compatibility than about 50% performance improvement. PyPy on the other hand starts from the path of 99% compatibility and then tries to improve performance (which started as 10000 times slower... and is now roughly 1.5 or 2 times slower). Just saying that the approach is completely different... And I have not much interest in it -- because you change the language and have to start again from scratch. A strong point of PyPy is that you don't have to; e.g. we have, in addition to the Python interpreter, a JavaScript, a Smalltalk, etc... A bientot, Armin. _______________________________________________ [email protected] http://codespeak.net/mailman/listinfo/pypy-dev
