Proof step 28 from proof validstatfields-class-01 (previous step)

initdone(class, st), tdname∃(str, class), mkfs(class0, ty, fieldvar) ' ∈ statfields(class), validstatfield(str, mkfs(class0, ty, fieldvar) ', st) ⊦ ty = void_type, jvmref -- mkfs(class0, ty, fieldvar) ' ∈ st ∧ type∃(str, ty) ∧ validval(str, st[jvmref -- mkfs(class0, ty, fieldvar) '], ty, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 21:
⊦ 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 27:
initdone(class, st), tdname∃(str, class), mkfs(class0, ty, fieldvar) ' ∈ statfields(class), is_fskey(mkfs(class0, ty, fieldvar) ') ∧ mkfs(class0, ty, fieldvar) ' ∈ statfields(mkfs(class0, ty, fieldvar) ' .fs .class) ∧ tdname∃(str, mkfs(class0, ty, fieldvar) ' .fs .class) ∧ (initdone(mkfs(class0, ty, fieldvar) ' .fs .class, st) → validfield(str, jvmref, mkfs(class0, ty, fieldvar) ', st)) ⊦ ty = void_type, jvmref -- mkfs(class0, ty, fieldvar) ' ∈ st ∧ type∃(str, ty) ∧ validval(str, st[jvmref -- mkfs(class0, ty, fieldvar) '], ty, st)
