default '==' on structs

Lars is right, the == among structs is broken still:

struct Foo { string s; }
void main() {
    string s1 = "he";
    string s2 = "llo";
    string s3 = "hel";
    string s4 = "lo";
    auto f1 = Foo(s1 ~ s2);
    auto f2 = Foo(s3 ~ s4);
    assert((s1 ~ s2) == (s3 ~ s4));
    assert(f1 == f2);
}
