I suppose if you find yourself doing heaps of swaps with complicated indexes it could be useful to have a swap primitive. In my experience it's a pretty rare thing to want to do, though. Also it only covers one special case of all possible permutations. It won't help you with a, b, c = b, c, a for example. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
