Sorry to have given this impression so much. I can only speak for myself: "hating" is a bit too strong; genereally speaking I have little interest for the "syntactic" side of programming language or language feature implementations (like AST restrictions or manipulations), and I am more interested in solutions that work at the "semantic" level, i.e. at the level of the behavior of objects (like Zope's security proxies, PyPy's various object spaces, and (at a lower level) PyPy's sandboxing). If I have real critics about RestrictedPython it's that it's not Python at all - it's a seriously limited sublanguage. Now I'm sure there are use cases for such a thing, and unlike Python's dead rexec, I can imagine that it can be made safe with enough care. Personally I have not much interested in that (but nothing against people that do). Sorry for the over-reaction. A bientot, Armin. _______________________________________________ [email protected] http://codespeak.net/mailman/listinfo/pypy-dev
