[swift-evolution] Proposal: Python's list, generator, and dictionary comprehensions

[Amir Michail]

Python examples:

l = [x*x for x in range(10)] // list comprehension

l2 = [(x,y) for x in range(10) for y in range(10) if x + y < 8] // another list comprehension

g = (x*x for x in range(10)) // generator comprehension

d = {x:x*x for x in range(10)} // dictionary comprehension


I think most programmers would like using these. They are concise and easy to understand.
