      Yeah. I didn’t understand what they meant by the wtf there. Seemed to me someone wondered if the Action would have a localised version of i (making this stay lowercase on a phone was harder than it should be) or if it used the same i. So made a simple test for it.

      Not really sure it’s a wtf unless they expected a different result.

        The compiler optimization example (IIRC #6) was unexpected, when just looking at the code
