I'm sorry, I haven't been very clear. I'm not even an expert on message-passing languages, but I see that it's a profound concept that hasn't been adequately integrated into the OOP model. In any case, I will try to do better. And I apologize to everyone on the list for the prior mail spam. A part of me is a bit giddy with the idea. By message passing, I mean all the ways we communicate to objects in the OOP environment. Usually we "communicate" to them through method-invokation. But this is the wrong way, I argue, to look at the problem. With function or method syntax, you're telling the computer to "execute something", but that is not the right concepts for OOP. You want the objects to interact with each other and in a high-level language, the syntax should assist with that. > By building it into the language, it would *enforce* a modular object > style, rather than the current, very specialized and very programmer > specific way there is now.

In what way would message passing enforce a modular > object style? In what way does Python not already have a modular object > style? Hopefully my paragraph clarifies that a bit. But the key conceptual shift is that by enforcing a syntax that moves away from invoking methods and move to message passing between objects, you're automatically enforcing a more modular approach.
