Marshall Cline describes a problem with multiple inheritance:

This is actually a specific instance of a more general problem.

Section 10.11c in E&S mentions the topic of ``Renaming'' and the problem of
finding an appropriate way to express the semantics of merging names from
multiple base classes. The status of inherited virtuals is similar.

Bjarne's current proposal for ``Overriding'' (the topic's been Renamed ;-)
addresses these concerns.

> A common C++'ism
One more vote to make it ``common'' -- this is exactly the approach we used
in The C++ Booch Components library.  Our paper at the ECOOPSLA conference
presents the design.

I'm looking forward to next month's presentation of Annotated C++, I think
it's important work.
