Generator expressions have generated (pardon the pun) a lot of interest 
and support and will be part of Python 2.4 with a syntax very similar 
to list comprehensions, but with parentheses instead of square brackets 
(and the parens are optional in some cases).  Between this and the new 
itertools module (in the standard library) lazy evaluation becomes very 
accessible in Python (with all the benefits it brings for memory use 
and speed).
