Is this because of Clang bug https://bugs.llvm.org/show_bug.cgi?id=44833#c5 ?  If so, that Clang bug is probably going to block a //lot// of Ranges implementation until it's fixed, anyway. @ldionne, do you have any guidance here? (1) Should libc++ aim to be the one standard library that works around this Clang bug, or should we just pressure Clang to fix their bug? (2) In the short term, assuming the bug won't be fixed tomorrow, how much should Chris work around Clang bugs in these patches versus just delaying the patches until Clang is ready?
