  I like the idea but I'm not sure that still solves the down casting
problem. Say I do some bit ops on a long type and want to get it
into an int size (for whatever reason and there are several), I need
somehow to tell python that it is not an overflow when I'm int()ing
the number. Perhaps int could take a second hidden argument. Be
able to do a:

  int(big_num, signed=1)

  which is pretty clear.
