Proof step 12 from proof initdone-rec (conclusion)

⊦ initdone(class ' + classes, st) ↔ initdone(class, st) ∧ initdone(classes, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ initdone(classes, st) ↔ (∀ class. class ∈ classes → initdone(class, st))
Proof step 11:
⊦ (∀ class0. class0 ∈ class ' + classes → initdone(class0, st)) ↔ initdone(class, st) ∧ initdone(classes, st)

Rule argument

[crewrite-arg: initdone-def , F , [st, classes] → [st, class ' + classes] ]
