List Comprehensions Enhancement

[Greg Ewing]

I have implemented some of the list comprehension syntax
ideas that were discussed a while ago.

Some examples:

nums = [1, 2, 3, 4, 5]
strs = ["Apple", "Banana", "Coconut"]

print [3 * x for x in nums]
print [x for x in nums if x > 2]
print [(i, s) for i in nums for s in strs]
print [(i, s) for i in nums for s in [f for f in strs if "n" in f]]
