I fail to see how conjunction_v is better. It seems to cause more template instantiations in the happy path.

MSVC has a throughput optimization that directly recognizes conjunction_v although I'm not sure how much of a difference the short-circuiting will make.

I'm mirroring this to the MSVC-internal repo - please notify me if any further changes are pushed.

Thanks for looking out for ways to improve build throughput - it's like catnip for programmers! 🐈 🐈‍⬛ 😻
