But if you add seq.items(), you had better add seq.keys() too, and seq.values() as a synonym for seq[:]. I guess the perceived advantage of adding seq.items() is that it supplies yet another incredibly slow and convoluted way to get at the for-loop index? "Ah, that's the ticket! Let's allocate gazillabytes of storage and compute all the indexes into a massive data structure up front, and then we can use the loop index that's already sitting there for free anyway to index into that and get back a redundant copy of itself!" .

That's a -1, right? <0.1 wink>
