I've spent a bit of time digging in to this, and I think it's actually impossible to do with the context manager semantics as they currently exist.
Specifically, there's no way to re-execute the body of a with statement, which is pretty important in this context[0].

This has come up before and there is some ongoing discussion here #18
And you are correct that this can't be done as originally suggested. We've talked about a few variants of this idea but I've never quite been able to make it work in a way that is a clear improvement to the status quo. FWIW, in the case where you are calling that 3rd party function in a single place, I recommend the decorating the function inline (as you do in your example above) as a best practice.
