Temporal's going to have a Temporal.Absolute.compare function suitable for Array.prototype.sort. By any chance, can we have some more comparison functions for existing data types, for similar uses?

Symbol.compareTo protocol

class Sample { constructor(value) { this.#internal = value } [Symbol.compareTo](b) { // returns `-1`, `0`, `1` if (input instanceof Sample) { return this.#internal < b.#internal ? 1 : -1 } return -1 } } const samples = [ new Sample(2), new Sample(1), ] samples.sort() // effect `Array.prototyp.sort` default behavior References: https://docs.microsoft.com/en-us/dotnet/api/system.icomparable.compareto?view=net-5.0 https://docs.oracle.com/e…
