    // By its very nature, you need to do something with side-effects within Stream.peek().
    // </editor-fold>
    // Hint 2:
    // <editor-fold defaultstate="collapsed">
    // The sequential and parallel streams have the same contents, but they will
    // probably end up processing the elements in a different order, even though
    // the output list is collected in the proper order (encounter order).
    // </editor-fold>
    // Hint 3:
    // <editor-fold defaultstate="collapsed">
    // Consider a thread-safe side-effect-supporting structure such as LongAdder.
    // Note that LongAdder's accumulation function must be order-dependent for it
    // to detect parallelism.
    // </editor-fold>
