Proof step 10 from proof initdone-rec (previous step)

⊦ (∀ class0. class0 = class ∨ class0 ∈ classes → initdone(class0, st)) ↔ initdone(class, st) ∧ initdone(classes, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ initdone(classes, st) ↔ (∀ class. class ∈ classes → initdone(class, st))
Proof step 9:
⊦ (∀ class0. class0 = class ∨ class0 ∈ classes → initdone(class0, st)) ↔ initdone(class, st) ∧ (∀ class. class ∈ classes → initdone(class, st))

Rule argument

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