elis-mode.el does. In this case, it's using find-func.el, which uses the 
information we have about Elisp environment at runtime.

Here's another example:

The point is on a foo.bar() call in a Java-like language. Or maybe C++.

bar is present in classes A, B and C.

If the parser knows the type of foo to be A, the backend employing it 
can bring us to the one definition. If, however, the backend returns the 
xrefs for A#foo, B#foo and C#foo, there's no way the UI could 
distinguish between them.
