Rename doesn't show conflict in interface mapping


public class Base : IEnumerable {
    public IEnumerator GetEnumerator() {
        throw new NotImplementedException();
public class Derived : Base, IWeird, IEnumerable {
    public void X() { }
interface IWeird {
    void X();
Rename X in the interface to GetEnumerator().
It will show no conflicts, even though this changes the derived type's interface mapping for IEnumerable.

Note - since we report a warning about hiding the base class version of GetEnumerator(), we don't think this is important to fix in the short term.

What if Derived.X() was shadowing an existing Base.X() and thus already has the new modifier?
You then (I think) wouldn't show any warning.

I'm not sure if that's a non-corner-case enough scenario to make a fix more important.
