Got something better:

auto reversed(T)(T t)
    if (isTuple!T)
{
    static if (is(T : Tuple!A, A...))
        alias RevTypes = Reverse!A;

    Tuple!RevTypes result;
    auto tup = t.tupleof;
    result.tupleof = Reverse!tup;
    return result;
}

void main()
{
    auto tup = tuple(1, "2");
    assert(tup.reversed == tuple("2", 1));
}

I'll make a pull shortly.

P.S. this is a compile-error: Reverse!(t.tupleof)

Might be worth filing this as a bug.
