title: define a new route alias in laravel 5.8
body: <p>I'm new to laravel. I'm using laravel 5.8 . I define a new route name called<code>signin</code> in <code>routes/web.php</code> and call it in my controller to redirect to this page. but laravel throw an exception with the error <code>"Method Illuminate\Routing\Redirector::signin does not exist</code></p>
  
  <pre><code> //.../routes/web.php
   Route::get('/registration', 'Mycontrollers@index')-&gt;name('signin');
  
  //in Mycontroller.php
  //some code
  public function index(){
  
   //some code
   return redirect()-&gt;signin();
  }
  </code></pre>
  
  <p>but if I used <code>return redirect()-&gt;route('signin');</code> it works fine</p>
