What is object-oriented programming? My
guess is that object-oriented programming will be in the 1980’s what
structured programming was in the 1970’s. Everyone will be in favor
of it. Every manufacturer will promote his products as supporting it.
Every manager will pay lip service to it. Every programmer will
practice it (differently). And no one will know just what it is. — Tim Rentsch, SIGPLAN
