Another illustration (foreach is in function now):
---
int func() {
    int[2] arr;
    int* ptr;

    void f() {
        //Error: variable __aggr3 is used before initialization
        foreach(i, ref p; arr) if(i == 0)
            ptr = &p;
    }

    f();

    int i = *ptr;
    return 0;
}

enum e = func();
