	I'm looking for help with a problem in Abelson & Sussman.
Exercise 2.5 calls for representing the integers as functions,
i.e., Church numerals.  The stated problem is fairly straight 
forward considering the hint.  My question or dilemma is what 
comes next? Given the functions, how do you manipulate them as 
numbers?  For example, how do you test for equality of two 
functions (integers)?  Am I just being dense?  Should this 
be obvious? Any help or pointers would be appreciated.
