Proof step 24 from proof validref-primarray (previous step)

junkrefs(str, refs, st[refs .first -- _type] .type, st), okarray(refs .first, ty, st), is_primtype(ty), refs .first ∈ st ⊦ refs .first = jvmref, refs = []

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 23:
refs = r + refs0, junkrefs(str, refs, st[r -- _type] .type, st), okarray(r, ty, st), is_primtype(ty), r ∈ st ⊦ r = jvmref, refs = []

Rule argument
