<Replying to the entire naming thread, not one message in particular> convert seems like the best word. To me. In all other cases (swap, flip, invert, reorder,...) I would expect something to *always* happen. Whereas with 'convert' I wouldn't be surprised when the operation is a no-op. ie a swap/flip/invert/etc that *sometimes* doesn't actually need to swap/flip/invert seems wrong to me. convert just says do whatever is needed. That may be swap or some more complicated reordering, or nothing. So I mentioned 'reorder' there. The mathematician in me will admit that the non-reorder is still a reordering, but between 'reorder' and 'convert' I still expect reorder to do something more specific than convert. convert can do nothing, in my mind. Feel free to discuss convert_to/from/in_place/etc... Tony
