Check here: https://gcc.gnu.org/projects/cxx-status.html which C++-20
features are supported by GCC 8
Before using them I think it would be a good idea to double-check if
those are also supported by the minimum version of Clang that we want to
And maybe also to check if those are supported by MS Visual C++ ?
I say maybe because I'm not sure if we support this compiler.
