It's not much worse, but it's not everything that's to tuples. Here's 
one more example:

Can't do it with tuple(a, b) = tuple(2, 3);
One would have to create yet another helper function, e.g.
 > ptuple(&a, &b) = tuple(2, 3);

Or perhaps something with 'ref' instead of pointers, but I remember it 
being buggy with tuples, and might be too dangerous, since you wouldn't 
see that you're passing pointers around
