Proof step 4 from proof validrefkeynotnull-no-newrefs (previous step)

st[r -- sk] .refval = r, validrefkeynotnull(str, r -- sk, ty, st), newref(r, st) ⊦ r = jvmref

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 3:
st[r -- sk] = refval(r0) ∧ is_referencevalue(st[r -- sk]), r0 = r, validrefkeynotnull(str, r -- sk, ty, st), newref(r, st) ⊦ r = jvmref

Rule argument

[speclemmaarg: is_referencevalue(val) ,r = val .refval ↔ val = refval(r) ,[val, r] → [st[r -- sk], r0] ,T ,javavalue , ,elim-refval ]
