New submission from Joongi Kim <[email protected]>:
This is just an idea: ContextVar.set() and ContextVar.reset() looks naturally
mappable with the "with" statement.
For example:
a = ContextVar('a')
token = a.set(1234)
...
a.reset(token)
could be naturally rewritten as:
a = ContextVar('a')
with a.set(1234):
...
Is there any particular reason *not* to do this?
If not, I'd like make a PR to add this API.
Naming suggestions of this API are welcome, but it also seems possible to keep
it "set()" if we retain the reference to the ContextVar instance in the Token
instance.
