I dunno. This is exactly what Cython does. I have exactly one extension module in Cython that uses it, and so very limited experience-- but it seems very solid and very safe, from my admittedly limited attempts at breaking it. True, Cython != Python. But its close enough that Python programmers can do it without knowing the pain of C, just following a certain limited Python subset. Its very doable, very accessible, and *seems* to address this very issue. -- Stephen Hansen ... Also: Ixokai ... Mail: me+list/python (AT) ixokai (DOT) io ... Blog: http://meh.ixokai.io/
