I ran into the issue of wanting an ordered dict recently. I was rather upset at having to redesign my data structures--at first. After reworking them to fit within the confines of an unordered dict, I realized that it actually worked better. 

This isn't to say there should be no such thing, but it really doesn't need to be a part of the standard library, imo. -1 vote for ordered dicts.
