[libcxx-commits] [PATCH] D107500: [NO MERGE][libcxx][ranges] Add `ranges::lazy_split_view`.

----------------
This is the main problem. It seems like there are a few places where the standard expects that `_View` is a forward_view that is default constructible. That requirement is never explicitly stated, though.

@CaseyCarter @cjdb do you have any insight into this?
