"Short-sighted users", "stupid language designers who believe too strongly in strong typing", "certainly can't be bothered to invent a useful concept for their short-sighted programmers", "dumb people who implement something the simple way, so it becomes complex and generally useless to everybody else", "unlike today's braindamaged CPU's", "just look at what C programmers do when they need lists! shudder".
