That triggered off something in my mind that's somewhat
different from what you went on to talk about.
So far we've been talking about ways of defining new
syntax. But operator overloading isn't creating new
syntax, it's giving a new meaning to existing syntax.
So the statement equivalent of that would be defining
new meanings for *existing* control structures!
For example, when you write
while expr:
...
it gets turned into
expr.__while__(thunk)
etc.
No, I'm not really serious about this -- it was just
a wild thought!
