moreover, according to Jim Hugunin, it's also an useful optimization in IronPython, that's why I decided to try it. Btw, I choose int+int for the example but in theory we could apply the same technique to other cases, says getitem on list and int or getattr on instances and string. I mean, they are the common cases so it might be worth of special casing them; of course not manually, that's not the pypy way :-). ciao Anto _______________________________________________ pypy-dev@codespeak.net http://codespeak.net/mailman/listinfo/pypy-dev
