Aside: You'll often hear people talking about "map-reduce" with big

map.__reduce__

Oh wait, that's nothing to do with reduce()...

That looks like a more serious map/reduce example. Mine came from a
double-take when I was looking at help(map) for some reason; there's a
__round__ magic method that helps define the round() function, there's
__abs__ for abs(), there's __str__ for str()... look, there's a
__reduce__ - it must be to help define reduce()! :)
That was my first think also. I believe __pickle__ or __unpickle__ would
have been more appropriate.
