Proof step 27 from proof init-put-nonvoid (previous step)

⊦ ty = void_type, init(str, st[r -- mkfs(class, ty, fieldvar) ', val]) ↔ init(str, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ init(str, st) ↔ (∀ class. tdname∃(str, class) → initdone(class, st))
Proof step 26:
⊦ ty = void_type, (∀ class0. tdname∃(str, class0) → initdone(class0, st[r -- mkfs(class, ty, fieldvar) ', val])) ↔ init(str, st)
