Proof step 39 from proof junkref-array (previous step)

st[r -- i '] = refval(refs .first), st[refs .first -- _type] .type ≤ st[r -- _type] .type .type, 0 < st[r -- _length] .intval, 0 ≤ i, i < st[r -- _length] .intval, is_array(str, r, st), junkrefs(str, refs, st[refs .first -- _type] .type, st) ⊦ refs .first = jvmref, refs = [], ∃ refs. refs ≠ [] ∧ refs .first = r ∧ junkrefs(str, refs, st[refs .first -- _type] .type, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 38:
refs = r0 + refs0, st[r -- i '] = refval(r0), st[r0 -- _type] .type ≤ st[r -- _type] .type .type, 0 < st[r -- _length] .intval, 0 ≤ i, i < st[r -- _length] .intval, is_array(str, r, st), junkrefs(str, refs, st[r0 -- _type] .type, st) ⊦ r0 = jvmref, refs = [], ∃ refs. refs ≠ [] ∧ refs .first = r ∧ junkrefs(str, refs, st[refs .first -- _type] .type, st)
