This code worked fine in 2.060, errors with 2.061 beta 1:

struct A
{
    enum zero = A(); // Error: A() is not an lvalue

    int opCmp(const ref A a) const
    //int opCmp(A a)
    {
        return 1;
    }
}

void main()
{
    A a;
    auto b = a > A.zero;
    assert(typeid(a).xopCmp !is null);
}

Obviously I could use a different signature for opCmp (e.g. the one I commented
out) but then the assert below will fail, as only the correct signature of
opCmp is accepted. Fixing either this bug or
http://d.puremagic.com/issues/show_bug.cgi?id=8561 would be good enough for me.
