Cool!

In the end (doesn't the PEP confirms this?) we decided to keep them
and make it a style rule instead. Some folks have generated data sets
using uppercase.

int("010") should return (decimal) 10.
int("010", 0) should raise ValueError.

I thought that was also in the PEP.

Anyway, with these tweaks, feel free to just check it in (well, if you
also fix the standard library to use the new notation).
