Doing it better 1999-05-27 b

From Reuben.

Putting my last point in more pragmatic terms, I have only rarely used
union types in C, and then in the same spirit as I use assignment within
expressions, simply because I can, and it makes things a little more
efficient.

Perhaps I'm missing something you want to do with unions in an OOP world,
like multiple inheritance, but I would have thought that inheritance can
be defined rather more tightly than a simple union, in such a way as to
avoid these problems.

Then again, I'm not convinced that multiple inheritance is a good thing; I
think you're better off using a context model than an object model if you
want that sort of thing.
