Collect modules that `use` some other module at compile time

Your problem sounds similar to protocol consolidation. You might find some inspiration in GitHub - OvermindDL1/protocol_ex: Elixir Extended Protocol · GitHub which has a custom mix compiler task that scans the beam files for modules that declare implemtations of a protocol.

I can easily add a function that returns all implementations of the given protocol too (I think I have it in a descriptor but it’s not really ‘public’ stuff?), but if that is the only feature you are needing then the normal elixir protocols already has that feature too.

But yeah, the scanner part itself could easily do that, copy it into your project and just have it be a compiler that generates the information necessary after everything else is already compiled.
