WebbLemmas and proofs by induction . Let’s say you wrote the factorial function and gave it the type nat-> nat.Later, you care about some other property about factorial, e.g., that if x > 2 then factorial x > x.One option is to revise the type you wrote for factorial and get F* to reprove that it has this type. But this isn’t always feasible. day of the dead zoe
