I think class/interface compatibility is not going to introduce trouble.
With the exception of COM, every interface IS an Object.

The missing compatibility makes the basic object functionality missing. 
That makes trouble with .toString as shown, with container that want to 
use opCmp/opEquals or functions that just want an Object of any type:

void store(Object o);

but i need a cast for interface:
store( cast(Object)a );

Yuck!
