I just realized that returning a sub-class of Int and/or Long would not 
be a problem here.  The recursion problem that I was guarding against 
only arose when the possibility of returning any object with an 
.__index__() method was suggested.

Therefore, I think these exact int or exact long checks can and should 
be replaced with PyInt_Check() and PyLong_Check().
