----------------
It took me a while to convince myself, but yes, I agree that Clang seems to 
implement the DR. I had to go back to P1787 to figure that out, but the key bit 
of new wording is:

> If a declaration named by a using-declaration that inhabits the target scope 
> of another declaration potentially conflicts with it ([basic.scope.scope]) 
> and either is reachable from the other, the program is ill-formed. If two 
> declarations named by using-declaration⁠s that inhabit the same scope 
> potentially conflict, either is reachable from the other, and they do not 
> both declare functions or function templates, the program is ill-formed.
