I might be misinterpreting the evidence, but sorting works on objects that define `__gt__` without `__lt__`. [...] The `<` operator try to use `__lt__`, but if it is not defined falls back to `__gt__`.
Thanks Serhiy, that makes sense. The docs for special methods say that `__gt__` is the reflected version of `__lt__`. Which brings me back to my original question: Since list.sort guarantees that it will only use the `<` less than operator, should we make the same guarantee for sorted, min and/or max? It would be odd if the guarantee applies to list.sort but not sorted. -- Steven
