Proof step 37:
st[r -- sk] = refval(r0), 0 < st[r -- _length] .intval, 0 ≤ sk .index, sk .index < st[r -- _length] .intval, is_indexkey(sk), is_arraytype(st[r -- _type] .type), fits(r0, sks0, st), is_bytevalue(st[r1 -- fs ']), is_array(str, r, st), junkref(str, r0, st) ⊦ r = jvmref, sks0 = [], sk = fs ', (st[r1 -- fs ', byteval(by)][r0 -- sks0]) = st[r0 -- sks0], junkref(str, r, st)
