Well fine. I should have realised the question was just a pretense and that there really never was any intention to consider the reactions, because the answer is already fixed. Of course a key function can always be written, it may just need a specific class to implement the specific order. Likewise there is no reason to expect the order-functions to preform worse when implemented in a class, rather than in a function. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list
