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
