Proof step 6 from proof nouninit-mode-01 (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 3:
⊦ nouninit(claset, st) ↔ (∀ class. class ∈ claset → ¬ initundone(class, st))
Proof step 5:
∀ class. class ∈ claset → ¬ initundone(class, st) ⊦ ∀ class. class ∈ claset → ¬ initundone(class, st)

Rule argument

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