Eh? I've been using it a hell of a lot!

std::variant is listed on GCC 7's page [0], and I know that is there in at least 7.1

I don't use clang much, but they list it as supported [1], and I believe the patch [2] landed in 5.0

Hmm, have to check include paths again!

So I glanced over this, and found that std::variant is in libc++, as you would expect, but in some cases, when you get a nice modern compiler, you might not end up with it linked to a nice modern stdlib.

So maybe some sort of mis-match got in your way.

Anyways, here's hoping you get to use C++17 in its full glory!
