Using `Nat.lt_trans` is too restrictive, and using `Nat.lt_of_lt_of_le` should make this tactic prove more goals. This fixes a regression probably introduced by #3991; at least in some cases before that `apply sizeOf_get` would have solved the goal here. And it’s true that this is now subsumed by `simp`, but because of the order that `macro_rules` are tried, the too restrictive variant with `Nat.lt_trans` would be tried before `simp`, without backtracking. Fixes #5027 |
