I see the point, but I think that having the 'reset' method defined on
the ContextVar class is easier to grasp. It also feels natural that a
pair of set/reset methods is defined on the same class. This is
highly subjective though, so let's see which option Guido likes more.

I think this came up in one of the previous reviews of the PEP. I like Yury's (redundant) version -- it makes it clear to the human reader of the code which variable is being reset. And it's not like it's going to be used that much -- it'll be likely hidden inside a context manager.
