There was a problem hiding this comment.
We were not handling constant receivers (e.g.: Foo.alias_method :bar, :baz), which ended up being surfaced in the new tests.

This PR extracts a portion of #697
The PR implements
follow_method_alias, which accepts adefinition_idfor an alias and follows the chain until reaching the first concrete method definition. This is required to exposeMethodDefinition#signaturesin the Ruby API (as the definition may be an alias).This PR also moves the core logic of finding members in the ancestor chain to
query.rs, so that we can reuse it for this implementation and for the FFI.
