    // We maintain a persistent cache of hook implementations in addition to the
    // static cache to avoid looping through every module and every hook on each
    // request. Benchmarks show that the benefit of this caching outweighs the
    // additional database hit even when using the default database caching
    // backend and only a small number of modules are enabled. The cost of the
    // $this->cacheBackend->get() is more or less constant and reduced further
    // when non-database caching backends are used, so there will be more
    // significant gains when a large number of modules are installed or hooks
    // invoked, since this can quickly lead to
    // \Drupal::moduleHandler()->hasImplementations() being called several
    // thousand times per request.
