Any recommendations on the best way to get the desired functionality? (C2 which is an I2 interface yet inherits the implementation from C1).
One way that seems to work is to add "C2::a() { C1::a(); }", but it doesn't seem quite right.
Speaking as a non-C++ language lawyer, I think that is what we have to
do. I guess this reinforces the fact that C++ is not java.

Hi Dave,
I would think that I1::a() is not virtual because it is defined in the
super
class C1. What is going on here?
I1::a was defined in super class C1 for the C1 half of the multiple
inheritance (via C2::C1::I2::defined a), but the I2 half's (via
C2::I2::I1::pure virtual a) a has not been concretely defined anywhere up
that inheritance chain.
HTH,
