I believe the context API design has gotten totally out of hand. I have a counter-proposal: let's drop context.

Heh. I was about to pull out the "if the implementation is hard to explain, it's a bad idea (and bad ideas shouldn't go into 2.X)" rule last week in response to the endless nick-phillip-paul "today I put in my brain the other way" threads... ;-)

(but the design isn't really that hard to explain; it's just that ever- one seems to be missing that there are three objects involved, not two...)

But if you think we can get rid of the "with statement context object" [1], I'm all for it. "explicit is better than implicit" etc.

+1.
