Proof step 6 from proof lookup-rec-refval (previous step)

is_referencevalue(st[r -- sks]) ⊦ sks = [], st[r -- sks] = st[st[r -- sks .first] .refval -- sks .rest]

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 5:
sks = sk + sks0, is_referencevalue(st[r -- sks]) ⊦ sks = [], st[r -- sks] = st[st[r -- sk] .refval -- sks0]
