CLion, which I consider an “IDE that works well”, does not do this. It has its own C++ frontend, which parses the code and does semantic analysis independent from the compiler, and a significant part of the IDE’s functionality is reliant upon that. I guess it would be quite problematic for them to implement module support as currently specified.

I haven’t been following this because I’ve left the CLion team a couple months ago, but I’m sure their feedback would be very valuable.
