Clarification:
It compiles fine with msvc

[ghost]

does -std:c++17 work in clang-cl? or should it be /std:c++17 ? I don't actually know anything about clang-cl, so i could be off base.

[HFDan]

cl and clang-cl allow both / arguments and - arguments

I just ran into this issue today as well, Im trying to figure out how to correct it.
