As the other answer said, nobody has (yet) an implementation of the _released_ standard, but both GCC and especially Clang have had modules very close to what stabilized by C++20 for years. You can enable them by specifying a flag (-fmodules-ts) on any recent release of Clang.

I know that but I'm just baffled that the text of the standard could be released at a point in time when nobody has succeeded at implementing it fully. That seems like it would almost guarantee that no one implements the standard as it's written, as there is no proof-of-concept that it's truly viable... I'd expect to see several revisions to this before C++23 as the compilers work out the issues.
