Hi @Erica_Sadun – discussion of SE-0203 should stay on the [review thread](https://forums.swift.org/t/se-0203-rename-sequence-elementsequal/11482). This thread is specifically for whether `Sequence` should be changed/augmented to differentiate between different notionally ordered and unordered iterable things.

There is some discussion of the case [for](https://forums.swift.org/t/se-0203-rename-sequence-elementsequal/11482/66)/[against](https://forums.swift.org/t/se-0203-rename-sequence-elementsequal/11482/69) eliminating the sequentially-equal method on that thread.
