The first one would place 4 at the start of the array. So would the second one. If you did the first, then the second one, two 4s would be placed at the start.

  But arrays start at -1. How would that work?

    You can insert items before the start

      So it’s not invariably true that arrays start at -1? They only start at -1 after an array literal assignment? You need to update the language description! ;)

        Perhaps they start at -1 and proceed in both directions

        const var scores = [3, 2, 5]! scores[0.5] = 4 print(scores) //[3, 2, 4, 5]! scores[-2] = 10 print(scores) //[10, 3, 2, 4, 5] print(scores[-1]) // 10 is how I interpret the spec, but I did not run this through the reference compiler yet.
