[PATCH] D48348: [ADT] Add zip_longest iterators.

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

Idle thought: Could/should this be composed from other primitives that could be created. Such as an infinitely long (or maybe bounded, not sure) range built from another range and a functor of some kind? (or such a thing specifically tailored for Optional-or-default-T situations) & then zip two of those together & bound that resulting infinitely long range (or bound the input ranges, either way).

Maybe that's overgeneralization, but just an idea to see how others feel about it.
