Mmm, nice - I thought at first the list assignment for $d and $e was a false economy, but on closer inspection, it somehow avoids the need for a temporary value for $d - care to explain to an idiot? (I assume that the new value for $d is not used in the evaluation of $e)

  ($d, $e) = (2*$d*$e+$a, $e**2-$d**2+$b);
