Let's take a step back. The documentation says to return a tuple between 2 and 5 elements long. You can omit the optional ones or use Nones in their place. The original code you posted allocated a 5-tuple, but did not insert anything into positions 2, 3, or 4. This was an error. You should have returned a 2-tuple of the type object in the 0-index slot and the argument tuple in the 1-index slot. Are you saying that you just returned the argument tuple? I don't think that would work. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
