btw, I don't see whare spec says that an aggregate can't hold both old and new
style members

struct C
{
    SOld sOld;
    SNew sNew;
}

void main()
{
    C c;
    auto d = c;
    assert(d.sOld.s);
    assert(d.sNew.s);
}

This is a buggy definition too and doesn't pass second assert too.

The spec doesn't say that this shouldn't work.
It just ignores this case. But this is definitely the language design bug.
