Proof step 2 from proof newrefs-rec-01 (previous step)

⊦ newref_list(m + 1, st) = newref(st) ' + newref_list(m, st[newref(st) -- 0 ', noval])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ newref_list(n + 1, st) = newref(st) + newref_list(n, st[newref(st) -- 0 ', noval])

Rule argument

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