Proof step 3 from proof at-put-other (previous step)

⊦ rk = jvmref -- sk, sks = [], (st[rk, val][jvmref -- (sk ' + sks)]) = (st[rk, val][st[jvmref -- sk] .refval -- sks])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ sks ≠ [] → st[r -- (sk ' + sks)] = st[st[r -- sk] .refval -- sks]

Rule argument

[crewrite-arg: lookup-rec-01 , F , [sks, sk, r, st] → [sks, sk, jvmref, st[rk, val]] ]
