A const value time is meaningful, it means that you are saying the D compiler
that you don't want to modify it. Generally it's good to stick a
const/immutable even when you use values inside your functions.

I think it works (it has the same problems of the const alone, there is no type
inference):
void main() {
int[3] array;
foreach (ref const(int) x; array) {}
}
