With C++20, orderings are finally getting a first-class post in the language. What are orderings, though? What are the basic best practices around them? What are they useful for? Where do they come from? What kinds are there? What do they represent? How do they play together? What are the representations of orderings? Is the current implementation so broken we'll just throw it out?

This talk will try to answer the above with a principled approach that explains both the mathematics of orderings and how we got where we currently are in the standard. It is the hope of the presenter to poke the audience enough to foster a discussion about missing features in the C++20 proposal, so that defects can hopefully be identified before C++20 ships.

The author is a co-author of quite a few committee papers on ordering, who has, in addition, worked with Alex Stepanov enough to have argued about ordering with him. This talk tries to illuminate the reasons for default ordering to be included in Regular in Elements of Programming, and the way the idea evolved to its current manifestation. This talk endeavors to be your definitive talk about the background of operator⇔.

Alternative aim: the talk wants to be necessary viewing on youtube. If you want your heckling to be heard, you should come. The presenter will be most pleased.
