Proof step 24 from proof isarray-keyin (previous step)

st[r -- sk] = refval(r0) ∧ is_referencevalue(st[r -- sk]), is_array(r0, st), i < st[r -- (sk ' + _length ')] .intval, 0 ≤ i, 0 < st[r -- (sk ' + _length ')] .intval ⊦ r0 -- i ' ∈ st

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 23:
st[r -- sk] = refval(r0), 0 < st[r -- (sk ' + _length ')] .intval, 0 ≤ i, i < st[r -- (sk ' + _length ')] .intval, is_array(r0, st) ⊦ r0 -- i ' ∈ st
