Well IIRC it was a tempting way to replace for-loops with direct list operations ala Python, Ruby etc. But the amount of syntactic noise and cognitive load seemed too much for the added leverage.

Our code had sufficient complexity that I didn't want one more oddity (as many would see it) to explain.

But for a small team, or a team that's all on the same page, maybe it's good.

Sorry to say there's no dramatic story of code explosion here!
