Thanks to someone that >wrote me noting this. Incidentally, I find the Smalltalk 'method' for >'procedure' not confusing; but surely the idea of 'sending' a 'message' >to an object is even more bizarre when the alternative of 'invoking a >method' is available. Sending a message does, indeed, invoke a method. But when you write the code that sends the message, you don't know *which* method it will invoke. That's polymorphism.
