Reading through the code, it seems to use a lot of code to provide quite basic sorting functionality. It feels like it's trying to fill the same role as sorted() does since Python 2.4.
The other features (locale-aware sorting, sort different keys using different algorithms / directions) are not easy to emulate using 'sorted()'
Locale aware sorting can be tricky, I'll have to look at that code again. Sorting different keys and directions are trivial with sorted(). I'm not sure what different "algorithms" mean, with sorted you implement a function that returns a sorting key, that sorting key is then used to sort. It should be possible to sort according to any algorithm that way.
Assuming an unsorted list of news stories, how would you use sorted to get them ordered by category (ascending) + publication date (descending)?
