Proof step 32 from proof isobj-addobj-04 (previous step)

fis .keys = instfields(class), validfieldinits(fis, st), sk ∈ instfields(class) ⊦ r = jvmref, goodfieldandtype(r, sk, addobj(r, class, fis, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 9:
⊦ goodfieldandtype(r, sk, st) ↔ is_fskey(sk) ∧ r -- sk ∈ st ∧ okval(st[r -- sk], sk .fs .type)
Proof step 31:
fis .keys = instfields(class), validfieldinits(fis, st), sk ∈ instfields(class) ⊦ r = jvmref, is_fskey(sk) ∧ r -- sk ∈ addobj(r, class, fis, st) ∧ okval(addobj(r, class, fis, st)[r -- sk], sk .fs .type)

Rule argument

[speclemmaarg: , goodfieldandtype(r, sk, st) ↔ is_fskey(sk) ∧ r -- sk ∈ st ∧ okval(st[r -- sk], sk .fs .type) ,[st, sk, r] → [addobj(r, class, fis, st), sk, r] ,F ,okfuns , ,good-field-def ]
