Yes, but this is where it breaks the OOP abstraction by 90 degrees.
By using function calls, you're telling the machine to do something.
But when you want to pass something to an object there should be a
natural way to do this for every object.  By using methods you pollute
the concept space with all sorts of semi-random (i.e. personal) names,
like append, add, enqueue, etc.

This proposal would not only make a consistent syntax across all
objects, but train the programmer to *think* modularly in the sense of
having a community of re-usable object.  I.e. "What should I do if
another object passes me something?".  No one thinks this now, because
the programmer expects new developers to learn *their* interface!
