why is it that bad? lol
It's just so ugly 😅
The keyword isn't pretty, but it's useful, easy to understand, and actually works correctly.
I'm sure you can think of something worse if you really try...
Well, obviously :)
It was more of a joke, but it's still pretty cringe to see it
The reason it exists is that reverse iteration over unsigned types is notoriously error prone. I think it's pretty nice to have this built in, knowing that it will be directly transformed into a simple for loop even in debug builds. It also allows easily reversing the order of iteration of any foreach loop, no matter which form. In particular, there is static foreach_reverse .
Although it's fallen mostly out of style, the reason I hated foreach_reverse is because it used to be applicable to delegate iteration, but just iterates forward (I've just checked and it's deprecated, but not disabled).
I think I can count on one finger (and you can guess which one) the times I've used foreach_reverse .
