Proof step 12 from proof validstatfields-validstatfield (conclusion)

⊦ validstatfields(str, st) ↔ (∀ class. tdname∃(str, class) ∧ initdone(class, st) → validstatfields(str, class, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ validstatfields(str, st) ↔ (∀ class. tdname∃(str, class) ∧ initdone(class, st) → validfieldlist(str, jvmref, statfields(class), st))
Proof step 11:
⊦ (∀ class. tdname∃(str, class) ∧ initdone(class, st) → validfieldlist(str, jvmref, statfields(class), st)) ↔ (∀ class. tdname∃(str, class) ∧ initdone(class, st) → validstatfields(str, class, st))

Rule argument

[crewrite-arg: validstatfields-def, F, [st, str] → [st, str]]
