Python has the special symbol "_" which is used exactly as a no-op (you could call it "foo" it you wanted, but "_" doesn't create new memory assignments) so you can expand arbitrary tuples without creating new symbols: a, b, c, _ = ('tuple', 'of', 'three') I like the proposal for D, but I fear it could be a source of bugs (you expect the tuple to expand to 4 values but silently is expanding to only 3, leaving the fourth unchangued).
