I also suspect that this function could be made more efficient. It
sorts the sequence. While sorting is very fast (thanks, Uncle Tim!) it

That would be the beauty of 638: if it's important to one piece of code,
it could be just enabled there. Of course the implementing macro would

But I'm under no delusions that this PEP will ever get accept
