Note that as listed in Bug 4053, struct constructors and opCall are not
compatible, so the v() syntax isn't possible. In the update to variant I've
been working on, I've added a .call method, which supports functions,
delegates, opCall, etc. Also, multi-argument opCall should be supported:

unittest {
    Variant v;
    int foo(int x, int y) { return x+y; }
    v = &foo;
    assert(v(4,6) == 10);
}
