What is the behaviour of ContextVar.reset(token) if the token was created
from a different variable? Raise an exception?
token = var1.set("value")
var2.reset(token)
The PEP states that Token.var only exists for debug or introspection.

Why ContextVar.reset(token) does nothing at the second call with the same
token? What is the purpose of Token._used? I guess that there is an use
case to justify this behaviour.
reset() should have a result: true if the variable was restored to its
previous state, false if reset() did nothing because the token was already
used. And/Or Token should have a read-only "used" property.
