Yep, clang, MSVC and GCC have all fixed compiler bugs found by Outcome.
It's been a good test of their compiler's C++ 14 conformance.

clang and GCC have also fixed the code optimisation problems I reported,
and Microsoft have told me it's a high priority for MSVC once their new
optimiser is debugged fully.

Oh no, it's definitely important to report ICEs in the compiler. Just
please don't judge Outcome harshly for it, just six months ago Outcome
was unusable on anything but clang. It's thanks to the compiler vendors
being so great with me that Outcome is now widely usable.
