I can't speak for others, but one reason I haven't written a object
programming book because it is damn hard to write a book, and too easy
to play tennis and enjoy my marriage. Another reason is that I just
keep plowing on, finding all kinds of reasons to like objects,
amazed at their unbelievable usefulness, and completely unaware of
these glaring limitations. Imagine how embarrassed I would be to write
a book that didn't even mention operator overloading! I would be the
laughing stock of the OO community. :-(

Cheers,

David
