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`.
