i really dislike this setup 😅 we should just have the right infcx available here.

Could we instead add a method fn infcx(&self) -> Option<&InferCtxt> to trait AstConv and use that here?

can you move the whole if let error reporting chain into a separate function (and module astconv/errors.rs). having this much error reporting in a function with relevant behavior makes it harder to read.

can you add an assert that qself_ty does not have infer vars in this branch.
