[swift-evolution] else clause for loops like that in Python

For an array, I would almost always use `if let` with `lazy.filter.first` or `indexOf`. The if branch is “found”, else is “not found”.

If that wasn’t suitable for some reason, I’d probably put the search loop like that in its own function or method and return early from inside the loop. If you reach the code after the loop, the search has failed.

I’m not saying it’s a useless feature, just that *I* can’t imagine using it.
