I'm thinking in the same lines. It would be nice if importC would 
be able to detect abstract C++ classes and convert them to 
extern(C++) interfaces. Then we have inheritance support to think 
of as well.

This proposal has a tendency to grow. It might be a useful tool 
and people will demand more of it all the time if it becomes 
popular. Implementing importC will open that can of worms.
