That's why I said "based on" -- under the hood, a C type is used, and IIUC, that type has been "long" for ages. And a long on Windows 64 (with the MS compiler anyway) is 32 bit, and a long on *nix (with the gnu compilers, at least) is 64 bits.

This doesn't expose itself to pure python (and sys.maxint is now gone) but it does get exposed in the C API, and in particular, when passing data back and forth between numpy and pure python (numpy doesn't support an unlimited integer like python), or working with buffers or bytearrays, or whatever in Cython.

I'm not sure "the builtin integer type" was the right term for what you're referring to.

You're talking about changing Py_ssize_t, right?
