Could anyone tell me how to prove this?

example (m n : Nat) (h : decide (m < n) = true) : m < n := sorry

I think it's called docs4#of_decide_eq_true

Mario Carneiro (Jan 25 2023 at 21:48):

or by library_search if you're into that kind of thing

Casavaca (Jan 25 2023 at 21:53):

Thanks.
Do you know how to tell library_search to print hints?
