I don't think this can work - there would be too many ways for the
"real" types to leak, anyway. People would come up with hacks
like reload(sys), and then complain that they have to use such
hacks.

I thought it was the ultimate goal of PEP 237 to unify int and long,
in all respects.

I'll do some benchmarking.
