I tried hard to understand what you were saying but I still see nothing that messages do and Java methods don't, or the other way around.
Everything you say is confusing to me, but I'll just pick on one:
> An Object-Oriented language according to Alan Kay (according to me) then is one where the only way objects can communicate with other objects is by calling methods i.e. by message passing, never by modifying the objects directly from their outside.
What guarantees that when I send a message to an object, that object won't decide to change itself in response?
In other words, that distinction you are trying so hard to build between message passing and function calling is nonexistent.
