Does it work on clang LLVM targeting the MSVC ABI?

If it does, then lack of MSVC support is a non issue. Just compile the
stuff using Yap and Hana with clang and link it into your other MSVC
compiled stuff. Done.

(Incidentally, I have been told that getting unmodified Hana working in
MSVC is intended for straight after getting unmodified Ranges working.
The Visual C++ team are on it, and I don't doubt they'll succeed soon
now, though it will surely take a while for Ranges or Hana based code to
become entirely stable on MSVC. As, indeed, we saw with the empty main()
function ICE with Outcome)
