By the way, have you already decided on the implementation model for
interfaces?  Do you plan to mirror the C++ ABI (which requires one
word in every object for each interface it implements), a "fat
pointers" model (where access-to-interface types include a pointer to
an interface descriptor and the object), or a hybrid (something based
on hashing, for example)?
