Proof step 10 from proof validstatfields-initundone (previous step)

statfields(class) = sk ' + sks, validstatfield(str, sk, st), sk ∈ statfields(class) ⊦ statfields(class) = [], initdone(class, st), tdname∃(str, class)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ validstatfield(str, sk, st) ↔ is_fskey(sk) ∧ sk ∈ statfields(sk .fs .class) ∧ tdname∃(str, sk .fs .class) ∧ (initdone(sk .fs .class, st) → validfield(str, jvmref, sk, st))
Proof step 9:
statfields(class) = sk ' + sks, is_fskey(sk) ∧ sk ∈ statfields(sk .fs .class) ∧ tdname∃(str, sk .fs .class) ∧ (initdone(sk .fs .class, st) → validfield(str, jvmref, sk, st)), sk ∈ statfields(class) ⊦ statfields(class) = [], initdone(class, st), tdname∃(str, class)

Rule argument

[crewrite-arg: validstatfield-storekey-def , F , [st, sk, str] → [st, sk, str] ]
