    //      note 1: Only works with user-defined functions, not built-in functions like void()
    //   example 1: array_walk ([3, 4], function () {}, 'userdata')
    //   returns 1: true
    //   example 2: array_walk ('mystring', function () {})
    //   returns 2: false
    //   example 3: array_walk ({"title":"my title"}, function () {})
    //   returns 3: true
