struct S {
    immutable A = 5;
    int x;
}

int main() {

    S s;
    assert(s.sizeof == s.x.sizeof);
    assert(s.sizeof == s.x.sizeof + s.A.sizeof);
    return 0;
}

before 2.067:
core.exception.AssertError at test.d(12): Assertion failure

after 2.067:
core.exception.AssertError at test.d(11): Assertion failure



I do not want to change any of the issue above, I just do not understand why
some breaking changes are OK, and some other are not so ok.
