Cheeky comments aside, the problem with this is that it conflates to
fundamental, very different desires: execute and pass-this-message.
While yes in my mind I can think of obj.method(data) as passing data
to my object, *I don't want to do it in my mind*. I want to do it in
the interpreter. That's a big difference, because *other programmers
can't read my mind* and THEY won't know if I'm passing data or
executing a function.
