Proof step 3:
⊦ fits(r, [], st)
Proof step 5:
st[r0 -- sk0] = refval(r1), is_arraytype(st[r0 -- _type] .type) → is_indexkey(sk0) ∧ 0 ≤ sk0 .index ∧ sk0 .index < st[r0 -- _length] .intval, is_classtype(st[r0 -- _type] .type) → sk0 ∈ instfields(st[r0 -- _type] .type .class) ⊦ (st[r -- sk, val][r0 -- sk0]) = refval(r1), r0 = jvmref, junkref(str, r0, st), junkref(str, r, st), is_referencevalue(st[r -- sk])
