When comparing structs that contain arrays with different memory addresses, but
the same contents, the comparison fails.

Case 1:

struct StringPair {
    string s1;
    string s2;
}

void main() {
    auto p1 = StringPair("foo".idup, "bar".idup);
    auto p2 = StringPair("foo".idup, "bar".idup);
    assert(p1 == p2);  // Fails
}

Case 2:

struct StringPair {
    uint[] s1;
    uint[] s2;
}

void main() {
    auto p1 = StringPair([1,2], [3,4]);
    auto p2 = StringPair([1,2], [3,4]);
    assert(p1 == p2);  // Fails
}
