 *  Breaking: Replace `SocketPolicy` with a new type, `SocketEffect`. It splits triggers (request
    start, response body, etc.) from effects (closing the socket, closing the stream, etc.).

 *  Breaking: Rename `RecordedRequest.sequenceNumber` to `exchangeIndex` and introduce
    `connectionIndex` on that type. These properties may be useful when testing features like

	// Find the field start and end indices.
	// Doing this in a separate pass (rather than slicing the string s
	// and collecting the result substrings right away) is significantly
	// more efficient, possibly due to cache effects.
