Proof step 3 from proof nouninit-mode (previous step)

⊦ (∀ class. class ∈ claset → ¬ initundone(class, st)) ↔ nouninit(claset, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ nouninit(claset, st) ↔ (∀ class. class ∈ claset → ¬ initundone(class, st))

Rule argument

[crewrite-arg: nouninit, F, [st, claset] → [st, claset]]
