> Have we really not understood OO at all

The problem is that whenever we think OO, visions of Alan Kay and Smalltalk float into our heads and suddenly Everything Is An Object. Numbers "know" how to add themselves to other numbers, strings "know" how to print themselves to standard output...

...insanity ensues. We wake up, write a blog post about how OO failed and discard it all, only to repeat the cycle when we notice that some of the sane things we're doing look entirely as if we were doing OO.
