% python -Q new

The python guys decided that int/int -> int was a mistake, but because
it's an incompatible change, the removal process has been long (hence
the -Q flag, or a from __future__ import).  In fact, I think they gave
up on making it the default before python 3.

I appreciate that haskell has differentiated from the beginning.
