That's a great feature. But even if it's available, I'd use swap, because:

* I wouldn't have to mention each variable twice
* It would use move-operations rather than copy operations

Parallel assignment is still useful for other stuff, like traversing the
fibonachi sequence with two variables :-)

(a, b) <- (b, a + b);
