  /*
   * In most cases, one only wants a single copy of a hook. On the other hand,
   * plugins that depend on other plugins, may want to make it easier for the
   * end-user to use the plugin, and call the setup function of the dependent
   * plugins too. In case the end-user calls the same setup function, we'd end up
   * with hooks registered multiple times.
   *
   * To avoid this, protection against double-registration has been introduced.
   * The `event_handler_hook_use` and `loop_hook_use` functions will only allow
   * one copy of the hook. The `event_handler_hook_append` and `loop_hook_append`
   * functions will, on the other hand, just append the hooks, and not care about
   * protection.
