Swift’s PermutationGenerator is misleadingly named. It's not about permutation at all. It's just indexing collection with an index sequence. It should be named something else and Swift should offer a real permutation generator like this: https://docs.python.org/3.4/library/itertools.html#itertools.permutations.
