I would like to discuss Tom Honermann’s paper P0804 (Impact of the Modules TS on the C++ tools ecosystem). The Modules TS says:

"It is implementation-defined whether the source for module interface units for modules ... is required to be available."

This has massive implications for those of us who develop IDEs, code analysis tools, etc. and need to communicate with the clang/gcc/msvc toolchains to resolve the code. Think e.g. “Go to Definition” button in an IDE. It does work for headers (including standard library headers) – also implementation-defined - varying from compiler to compiler and not standardised. I’d like to gain a better understanding of how it will work with modules.

The paper is scheduled for EWG on Wednesday, but I think there is significant overlap with SG15.
