Interesting -- somehow this message came through on the google group mirror of  python-ideas only -- so replying to it barfed.

He's my reply again, with the proper address this time:

Hundreds of people want an orderedset (http://stackoverflow.com/questions/1653970/does-python-have-an-ordered-set) and yet the ordered sets that are in PyPI (oset, ordered-set) are incomplete.  Please consider adding an ordered set that has *all* of the same functionality as set.

 

(If anyone wants to add a complete ordered set to PyPI that would also be very useful for me!)

It seems like a good way to go here is to contribute to one of the projects already on PyPI -- and once you like it, propose that it be added to the standard library.

And can you leverage the OrderedDict implementation already in the std lib? Or maybe better, the new one in PyPy?
