In the examples we use a `MSS` type, which is a `map[string]string` that is `msgp` serializable.

```go
    handler := func(request *grid.MSS) (*grid.MSS, *grid.RemoteErr) {
        fmt.Println("Got request with field", request["myfield"])
        // Do something with payload
        return NewMSSWith(map[string]string{"result": "ok"}), nil
    }
	
    // Create a typed handler.

	scanner := bufio.NewScanner(strings.NewReader(input))
	scanner.Split(onComma)
	for scanner.Scan() {
		fmt.Printf("Got a token %q\n", scanner.Text())
	}
	if err := scanner.Err(); err != nil {
		fmt.Fprintln(os.Stderr, "reading input:", err)
	}
	// Output:
	// Got a token "1"
	// Got a token "2"
