Oh, allright. let's just call it a *little* easier, then. I mainly like 
the lispy flavour. Also, as a small extra bonus, you can use 
expressions with the tuple-notation. That allows you to do things like:

   #global constants
   base1 = 100
   base2 = 200

   #Someplace else
   xx = enum(('foo',base1), 'foo2', 'foo3', ('bar',base2), 'etc')


Of course, you can always eval() the right hand part of 'foo=base1', 
but the other form catches any syntax errors in those expressions 
before the program actually runs.
