Proof step 63 from proof unchNorec-junkrefs (previous step)

junkrefs(str, r ' + refs0, ty, st), ∀ str, ty, st, st0. junkrefs(str, refs0, ty, st) ∧ (∀ r. r ∈ refs0 → unchangedNorec(r, st, st0)) → junkrefs(str, refs0, ty, st0), ∀ r0. r0 = r ∨ r0 ∈ refs0 → unchangedNorec(r0, st, st0) ⊦ junkrefs(str, r ' + refs0, ty, st0)
