We agreed yesterday that the dictionary() constructor would accept a a list of two-tuples (strictly speaking an iterable object of iterable objects of length 2). That plus list comprehensions pretty much covers the territory of dict comprehensions:

print dictionary([(i, chr(65 + i)) for i in range(4)]) {0: 'A', 1: 'B', 2: 'C', 3: 'D'}

Wouldn't it be nice to be able to spell that

{ i: chr(65 + i) for i in range(4) }
