Indeed, although it might (or might not) be more useful to produce a 
Rational module as in SmallTalk, using Python longs for the two parts of 
the fraction.  Either or both would have a place.  But I have neither 
time nor need.  [And the SmallTalk idiom makes dealing with Rational 
easier than it would be in Python, I think.]
