Unresolved Question

• An alternative would be to use a more general "gotoSuper" request, which would work for super methods, super classes and super modules. This is the approach IntelliJ Rust is takeing. However, experience shows that super module (which generally has a feeling of navigation between files) should be separate. If you want super module, but the cursor happens to be inside an overriden function, the behavior with single "gotoSuper" request is surprising.

Start by reviewing the proposed experimental/parentModule request and the existing language server protocol conventions in this repository. The issue provides no file or test entry point; done would require resolving the separate parent-module versus general gotoSuper design and updating the protocol accordingly.
