Kim Morrison 6893913683 feat: replace List.lt with List.Lex (#6379) ... This PR replaces `List.lt` with `List.Lex`, from Mathlib, and adds the new `Bool` valued lexicographic comparatory function `List.lex`. This subtly changes the definition of `<` on Lists in some situations. `List.lt` was a weaker relation: in particular if `l₁ < l₂`, then `a :: l₁ < b :: l₂` may hold according to `List.lt` even if `a` and `b` are merely incomparable (either neither `a < b` nor `b < a`), whereas according to `List.Lex` this would require `a = b`. When `<` is total, in the sense that `¬ · < ·` is antisymmetric, then the two relations coincide. Mathlib was already overriding the order instances for `List α`, so this change should not be noticed by anyone already using Mathlib. We simultaneously add the boolean valued `List.lex` function, parameterised by a `BEq` typeclass and an arbitrary `lt` function. This will support the flexibility previously provided for `List.lt`, via a `==` function which is weaker than strict equality.		2024-12-15 08:22:39 +00:00
