// Wrap returns a wrapped version of w that provides the exact same interface
// as w. Specifically if w implements any combination of:
//
// - http.Flusher
// - http.CloseNotifier
// - http.Hijacker
// - io.ReaderFrom
// - http.Pusher
//
// The wrapped version will implement the exact same combination. If no hooks
// are set, the wrapped version also behaves exactly as w. Hooks targeting
// methods not supported by w are ignored. Any other hooks will intercept the
// method they target and may modify the call's arguments and/or return values.
// The CaptureMetrics implementation serves as a working example for how the
// hooks can be used.
