Proof step 10 from proof is_array-addarray-01 (previous step)

val ∈ vals, is_array(str, r, addarray(r, mkclasstype(class), vals, st)) ⊦ is_referencevalue(val)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ val ∈ vals ↔ (∃ n. n < # vals ∧ vals[n] = val)
Proof step 9:
∃ n. n < # vals ∧ vals[n] = val, is_array(str, r, addarray(r, mkclasstype(class), vals, st)) ⊦ is_referencevalue(val)
