yes, I'm aware of composites (and of the sad fate of Records and Tuples) and I'm hopeful they will improve things. One thing that I'm not getting from the spec is the behavior of the equality semantics in case a Date (or a Temporal object) is part of the object. In other words, what is the result of Composite.equal(Composite({a: new Date(2025, 10, 19)}, Composite({a: new Date(2025, 10, 19)})? What is the result of Composite.equal(Composite({a: Temporal.PlainDate(2025, 10, 19)}, Composite({a: PlainDate(2025, 10, 19)})?
