-1

I don’t like the proposal.  I understand the flexibility it gives to rearranging elements but to someone reading the code it looks like an element was removed by mistake.

I don’t think it needs to change at the expense of making code look like an error was made.

No.

I’ve seen this in .plists and other languages.  I don’t use it for the reasons mentioned.

Quick review.
