I guess I don't understand what the interface is solving if you're
creating an interface _and_ a trait, why not just create the trait? It
sounds like you're coupling your interface to a specific
implementation and trying to get multi-inheritance out of PHP. This
seems like a design issue, and this RFC seems like a back-way to
multiple inheritance. Why not just allow multiple inheritance?

As a user of abstract classes since the early days of C++, I disagree.

I'd love to see a concrete example, but to me, this just seems like a
bandaid on an architectural smell.
