I agree on the performance characteristics. But if your using `get` then it doesn't matter that keyword lists have non-unique keys. You just get the first one.

  Maybe it does, maybe it doesn’t. Maybe somebody gave you a keyword list that they thought had unique keys and it didn’t. The point is, the two structures are not semantically equivalent, and I think it’s a mistake to conflate them in general. Just because you can use access syntax on both doesn’t mean you should write a polymorphic function that does so. Sometimes you should! But not most of the time.

    No, it literally returns you the first one. If you have a keyword list and use get your not going to be getting the benefit of duplicate keys.

      No, you asserted it doesn't matter because it still works and returns the first value. I was saying it might. The point stands. Different data structures, different modules, different semantics. Can and should is an important distinction here.
