Specifically, the problem is that static arrays have a fixed length, which
means that you can't pop elements off as is required for ranges. Dynamic
arrays on the other hand are ranges (at least as long as you import
std.range.primitives to get the range functions for dynamic arrays). Slicing
a static array gives you a dynamic array which is a slice of the static
array. So, mutating the elements of the dynamic array will mutate the
elements of the static array, but the dynamic array can have elements popped
off as is required for ranges, whereas the static array can't.
