During implementation, the meanings of "context" and "context manager" were swapped from the meanings in the approved PEP, leading to the current situation where decimal.Context is actually not, in fact, a context. That's rather disappointing. I liked the way that decimal.Context was a context. Was there a conscious choice to swap the terms, or did it happen by accident?

That's what I'm currently trying to find out - whether or not this was a deliberate decision made at PyCon. Conference sprints are great for getting things done, but they do occasionally lead to decisions getting made without being properly recorded :)

The terminology in the current docs is more natural in some ways than what the PEP settled on (mainly due to the context method), so I'm wondering if the downside that lead us to pick the slightly more awkward terminology may have been forgotten at the time of implementation.

Unfortunately this kind of discussion can take days via email*, even though it would probably only take ten minutes or so in person - not getting any immediate feedback when your point of view isn't being understood really slows things down.

I'm just glad AMK noticed the discrepancy - I completely missed it when I read the contextlib docs (I suspect my brain was being 'helpful' and automatically filled in what I expected to see rather than what was actually there).

Cheers, Nick.
