If `bar` is a slice then the short syntax isn't that useful (although it's shorter than the three-clause for loop equivalent).
But if `bar` is a map or a channel, then that short syntax is very handy.
For comparison's sake, you don't see many PHP users complaining about the difference between `foreach($bar as $foo)` and `foreach($bar as $_ => $foo)`.
I'd also be fine with it if they switched the ordering of the tuple so that only unpacking one thing gave you the element instead of the index. My point is mainly that the behavior you get currently with a slice is not what you want 9 times out of 10.
