Proof step 5 from proof newrefs (previous step)

is_newref_list(r ' + jvmref ', st) ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ is_newref_list(refs, st) ↔ ¬ dups(refs) ∧ (∀ r. r ∈ refs → newref(r, st))
Proof step 4:
¬ dups(r ' + jvmref ') ∧ (∀ r0. r0 ∈ r ' + jvmref ' → newref(r0, st)) ⊦

Rule argument

[crewrite-arg: list_ok, F, [st, refs] → [st, r ' + jvmref ']]
