We'd need a trick to deny an interface that would be inherited by
default. Something like private inheritance.
There's also the ambiguity of inheriting from a single interface: does
that create a sub-interface or an implementation of the interface?
Of course with your C++ hat on you probably don't care. On Mondays,
Wednesdays, Fridays and alternating Sundays I don't care either.
