Huh?, No the programmer has to think of how data interacts with
his/her objects. It's just that *now* the language is wise enough to
teach them to think about it.

You bring up an interesting subject. I think you could get rid of the
__call__ special method on objects. I think this is the wrong view
into the object universe or *data ecosystem*.

You're right, perhaps there's a better set of symbols that suggest
"moving data".
