Joe Jevnik added the comment: I was unable to see a performance increase by playing with the itemgetter.__call__ code; however, updating the propery code seemed to show a small improvement. I think that for simple indexing the cost of checking if it is a sequence outways the faster dispatch (when using PySequence_GetItem). I can play with this further.
