Yes, but usually not so much in function arguments but more in list-comprehensions or other places where unpacking was useful. I love the feature - I just don't have nested enough data to use it more :) What python offers in this respect can be seen as a limited form of pattern-matching known from functional programming - and instead of beeing considered an atrocity it's actually frequently requested to be enhanced. -- Regards, Diez B.
