Hey Saar! (CC the other devs)

Good to hear from you!

Interesting: we've never ever removed a compiler before as it breaks any existing URLs that used it. As the author I think you probably have the best ideas on this: I'm broadly more in favour of keeping it and putting a pop-up warning (which we can do)

Does that sound ok?

Congrats on getting merged!! :)

Hey, how's it going?

The clang-concepts repository is now obsolete, and all of concepts has been merged to clang trunk under the -std=c++2a/c++20 flag, and development is continuing there.
I think it'd be best to remove the experimental concepts branch from CE, or at least show a warning advising the user to use clang-trunk or clang-10.

What do you think?

Thanks again so much for hosting my build <3

We'll do our best: I'm not sure we (currently!) have a way to make it red...but we'll see:) thanks!

Pop up warning would be great!
Something like "WARNING : Concepts support has been merged to Clang trunk - please use it with -std=c++2a for the most up-to-date support".
And please make it red or something 😛
