Proof step 8 from proof validstatfields-put-statfield-03 (previous step)

validstatfields(str, sks, st), mkfs(class, ty, fieldvar) ' ∈ sks, ¬ mkfs(class, ty, fieldvar) ' ∈ statfields(class) ∨ ¬ tdname∃(str, class) ⊦ ty = void_type, validstatfields(str, sks, st[jvmref -- mkfs(class, ty, fieldvar) ', val])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ validstatfields(str, sks, st) ↔ (∀ sk. sk ∈ sks → validstatfield(str, sk, st))
Proof step 7:
∀ sk. sk ∈ sks → validstatfield(str, sk, st), mkfs(class, ty, fieldvar) ' ∈ sks, ¬ mkfs(class, ty, fieldvar) ' ∈ statfields(class) ∨ ¬ tdname∃(str, class) ⊦ ty = void_type, validstatfields(str, sks, st[jvmref -- mkfs(class, ty, fieldvar) ', val])

Rule argument

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