* This is a simplified version of `wireTap(Sink)` that takes only a simple procedure.
* Elements will be passed into this "side channel" function, and any of its results will be ignored.
*
* If the wire-tap operation is slow (it backpressures), elements that would've been sent to it will be dropped instead.
*
* This operation is useful for inspecting the passed through element, usually by means of side-effecting
* operations (such as `println`, or emitting metrics), for each element without having to modify it.
