167−times and aren't automatically paired up, but you can recover the
168−relationship by tagging the requests.

170−So far we have used an `Event t ()` to trigger sending a request. If we choose
171−e.g. `Double` for the third `Proxy` argument to `client`, then `Event t Double`
172−will be used to trigger requests, and each `ReqResult` will carry the tag of
173−its request. Imagine we wanted to display not just the last "double" from

204−`Servant.Reflex.Multi` provides an alternative client-generation function
