Currently it's allowed to have nested struct fields in static struct (or global
templated structs):
---
void main() {
    int i;
    struct NS {
        int n;     // Comment to pass all asserts
     // int n2;    // Uncomment to fail assert on line 19
        int f() { return i; }
    }

    static struct SS1 {
        NS ns;
    }
    SS1 ss1;
    assert(ss1.ns != NS.init);

    static struct SS2 {
        NS ns1, ns2;
    }
    SS2 ss2;
    assert(ss2.ns1 != NS.init); // line 19
    assert(ss2.ns2 != NS.init);

    static struct SS3 {
        int i;
        NS ns;
    }

    SS3 ss3;
    assert(ss3.ns != NS.init);

    static struct SS4 {
        int i;
        NS ns1, ns2;
    }

    SS4 ss4;
    assert(ss4.ns1 != NS.init); // fails
    assert(ss4.ns2 != NS.init); // fails
}
---

Exactly same behavior for global templated structs like
`struct SS1(T) { T ns; }`.
