[libcxx-commits] [PATCH] D71994: SFINAE span default constructor on Extent == 0

[Michael Schellenberger Costa via Phabricator via libcxx-commits]

miscco added a comment.

Library concepts are not yet implemented.

I had a look at it over the weekend. The problem is that requires expressions are not yet implemented so we cannot even add those concepts yet. I didnt find out how to pass `-fconcepts` to gcc-9 in LIT and was too lazy to build everything on windows with MSVC.

So I would keep them as a todo?
