Proof step 65 from proof unchNorec-junkrefs (previous step)

junkrefs(str, refs, ty, st), ∀ r. r ∈ refs → unchangedNorec(r, st, st0) ⊦ junkrefs(str, refs, ty, st0)

User applied rule structural induction

And obtained the following new goals

Proof step 64:
∀ str, ty, st, st0. junkrefs(str, refs0, ty, st) ∧ (∀ r. r ∈ refs0 → unchangedNorec(r, st, st0)) → junkrefs(str, refs0, ty, st0), junkrefs(str, r + refs0, ty, st), ∀ r0. r0 ∈ r + refs0 → unchangedNorec(r0, st, st0) ⊦ junkrefs(str, r + refs0, ty, st0)

Rule argument
