As far as I can tell, this can be allowed without compromising safety:

----
void main() @safe
{
    static struct S
    {
        int value;
        int* pointer;
    }

    /* explicit `scope`: */
    scope S s1;
    scope int* p1 = &s1.value; /* Error: cannot take address of scope local */

    /* inferred `scope`: */
    int x;
    S s2 = S(0, &x);
    int* p2 = &s2.value; /* Error: cannot take address of scope local */
}

The `scope` on `s1` and `s2` really just applies to the `pointer` field. It can be ignored for the `value` field.
