Also a thought on terminology. Even though it seems I may have been the person who thought it up originally, I'm not sure I like the term "manager". It seems rather wooly, and it's not clear whether a "context manager" is supposed to manage just one context or multiple contexts.

I think getting rid of context should clear up most of this confusion (which is further evidence that Guido is making the right call). Once that change is made, the context expression in the with statement produces a context manager with enter and exit methods which set up and tear down a managed context for the body of the with statement. This is very similar to your later suggestion of context guard and guarded context.

I believe this is actually going back to using the terminology as you originally suggested it (one concrete object, one abstract concept). We really only got into trouble once we tried to add a second kind of concrete object into the mix (objects with only a context method).

Cheers, Nick.
