No, Apple designed them for Objective-C initially, so some support was added to clang for all C languages, based on module maps.

Google improved that implementation for C++ and has a private implementation of it in use.

Gabriel dos Reis picked up some ideas from a former work he did together with Bjarne for MSVC++.

The ongoing C++ Modules TS is to merge the ideas from both sides into what will become C++ Modules.

Hmm, I suppose I was talking about the specific work to integrate modules in to the C++ standard. I recall hearing from Bjarne at a STAC talk he gave a year (or so) ago that he and Herb had been coordinating effort between MS and MSFT to use Modules in the Microsoft toolset to improve compiler performance.

The history of modules you provided is helpful though, thanks.
