this solves part of the 'code duplication' problem. Might get a bit tricky
if you just want to define a few additional methods for some classes
(for example 'generator versions' of methods otherwise returning lists).

Ah, and by the way how is

	sys.version[:2] >= (x,y) 

supposed to work? On my python 2.2 

	sys.version[:2] == '2.'   is True

am i missing something here?
