[docs] [issue23677] Mention dict and set comps in library reference

[Josh Rosenberg]

Josh Rosenberg added the comment:

Heck, with the addition of additional unpacking generalizations in 3.5, you can make an empty set even without a comprehension: {*()}

Not really recommending the "one-eyed monkey operator", but the addition of unpacking generalizations undoes several of the limits on literals that previously existed.
