    //      note 1: Depends on call_user_func_array which in turn depends on the `cb` that is passed,
    //      note 1: this function can use `eval`.
    //      note 1: The `eval` input is however checked to only allow valid function names,
    //      note 1: So it should not be unsafer than uses without eval (seeing as you can)
    //      note 1: already pass any function to be executed here.
    //   example 1: call_user_func('isNaN', 'a')
    //   returns 1: true
    return callUserFuncArray(cb, parameters);
