Sorry, I don't follow.
Access to members from outside of the traits would require accessing the
concrete type. Since the approach I described used source
transformation, then this would just be a normal data member access, as
efficient as single inheritance.
Oh, source transformation. I didn't read closely. That won't work as a
replacement for single inheritance because it doesn't provide truly
existential types--for example, an array of heterogeneous objects all of
which share a common prefix.
