It was getcontext() in an earlier version of PEP 567. We changed it to copycontext() believing that that would clarify that you get a clone that is unaffected by subsequent ContextVar.set() operations (which affect the current context rather than the copy you just got).

Ah thanks. In which case, simply changing the emphasis to avoid the implication that Context objects are immutable (while that may be true in a technical/implementation sense, it's not really true in a design sense if ContextVar.set modifies the value of a variable in a context) is probably sufficient.

[The discussion is fragmentary because Yury is on vacation until the 15th and I am scrambling for time myself. But your long post is saved, and not forgotten.]

OK. I knew you were short on time, but hadn't realised Yury was on vacation too. Sorry if I sounded like I was nagging. Paul
