Hi.
Straight to the point: I'd like to make a case for a __disconnect__
interface, like __connect__.
My use case is: I have a small library that wraps Google, Yahoo, etc
maps. I'm very happy that I don't need to listen for events I don't
need; I can call GEvent.bind() or its analogue on the __connect__
method. But I never "unlisten", since there is no __disconnect__.
(Actually, I did an ugly hack on the event handler to check if the event
is disconnected, but that's not quite ideal.)
Patch follows:

then they seem improbable, and then, when we
summon the will, they soon become inevitable.
