Proof step 9 from proof newrefs-in (previous step)

r ∈ st, r ∈ newref_list(m + 1, st), ∀ r0, st0. ¬ r0 ∈ st0 ∨ ¬ r0 ∈ newref_list(m, st0) ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ newref_list(n + 1, st) = newref(st) + newref_list(n, st[newref(st) -- 0 ', noval])
Proof step 8:
r ∈ st, r ∈ newref(st) + newref_list(m, st[newref(st) -- 0 ', noval]), ∀ r0, st0. ¬ r0 ∈ st0 ∨ ¬ r0 ∈ newref_list(m, st0) ⊦

Rule argument

[crewrite-arg: newrefs-succ, F, [st, n] → [st, m]]
