With approx OFF the import is excluded and compile fails with E0425. Latent for as long as the file existed (since PR #73 era); never surfaced because no CI matrix combination ran `--features rayon` without approx. W-I4's new `hpc-stream-parallel` job exercises exactly that combination and tripped the failure. Fix: replace `assert_equal(cloned(&a), x)` with `assert_eq!(a, x)` — both `a` and `x` are `Array` and the file's other tests already use direct `assert_eq!`. Trim the now-dead `assert_equal, cloned` from the still-needed (test_par_azip3) `enumerate` import.
