The Python 3 merge of int and long has effectively penalized
small-number arithmetic by removing an optimization. As we've seen
from PEP 393 strings (jmf aside), there can be huge benefits from
having a single type with multiple representations internally. Is
there value in making the int type

Python 3's int is faster than Python 2's long, but slower than Python

I'm inclined to say it's not worth the trouble. If
