Proof step 8 from proof unchanged-validrefs-unchNorec (conclusion)

⊦ unchanged(str, refs .first, st, st0) ∧ validrefs(str, refs, ty, st) ∧ r0 ∈ refs → unchangedNorec(r0, st, st0)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 7:
r0 ∈ refs, validrefs(str, refs, ty, st), unchanged(str, refs .first, st, st0) ⊦ unchangedNorec(r0, st, st0)
