In the September SIGPLAN Notices there is an article, A Practical
Example of Multiple Inheritance in C++, by Wiener and Pinson.
Unfortunately, they got it completely wrong, so if you haven't seen
it, don't bother, and if you have seen it and couldn't make sense out
of it, don't worry.

Their example is an IntegerArray type that syntactically inherits from
two base classes, Array and Integer, but actually the Integer base
class contributes nothing, and the Integer-ness of the derived class
is due entirely to member functions in the derived class.

We will publish a response to their article, with a correct example,
in a forthcoming issue of SIGPLAN Notices.
