That makes me sad.

  Curious why? Clearly this is a landmine that many people step on. Why not remove it?

    To the extent this creates a performance penalty, it's a little annoying that a few systems create a behavior dependency that is not truly needed in a core type when there is a separate type that implements the desired semantics. But then again if it doesn't make it slower it should be fine.

      Fwiw, the way Raymond re-implemented dictionaries made them more efficient (the algorithms are the same, but it's now much more cache friendly), and had the side effect of making them ordered. He and many others advocated for having the ordering guaranteed going forward.

        And now they're locked into an implementation that is order-preserving, even if an optimization tomorrow could eke out another 10%, if ordering was not guaranteed.
