Are you sure? 'foreach' with a tuple as aggregate is automatically 
unrolled. Sort of a "static foreach", really. So it's not actually a 
loop. In fact, the index is a compile-time constant.
I'm not sure how the compiler handles this, but I suspect the optimizer 
may not even know it used to be any kind of loop at all...
