A use for integer quotients

The PEP proposal is to separate the current mixed meaning of / into
two new, unmixed meanings, one assigned to / and the other to //.  The
alternative suggested above and by others is not merely to switch
meanings but to keep the mixed meaning while adding one and only one
unmixed meaning.  It does not break code but has other problems.
