     *  * The method name to call (priority defaults to 0)
     *  * An array composed of the method name to call and the priority
     *  * An array of arrays composed of the method names to call and respective
     *    priorities, or 0 if unset
     *
     * For instance:
     *
     *  * ['eventName' =&gt; 'methodName']
     *  * ['eventName' =&gt; ['methodName', $priority]]
     *  * ['eventName' =&gt; [['methodName1', $priority], ['methodName2']]]
     *
     * The code must not depend on runtime state as it will only be called at compile time.
     * All logic depending on runtime state must be put into the individual methods handling the events.
