🟢	Tested with	aiken v1.1.0	✔️

Usage Example

use string_util/cbor.{print}

test should_unlock() {

    // arrange:
    let datum = datum.new(42)
    let redeemer = redeemer.new(42)

    // trace:
    trace print("Datum", datum)
    trace print("Redeemer", redeemer)

    // assert:
    unlock(datum, redeemer, 42)
}

will give something like,
