+1 The advantage is that the code becomes easier to understand if everyone uses the same parameter order. The disadvantage is that users don't have as much freedom to re-order the parameters as they like. I think the advantage weighs more. Furthermore, having different parameter orders in the same program could probably give the impression that the parameter order is important. If only one parameter order is possible, there can be no confusion regarding that.

Yes.

Yes.

Haven't used.

Read the proposal, imagined some friends discussing how the parameters should be ordered for a particular function, and thought "let's remove this trap from the language."
