FWIW: You can also define such an `assign_to()` function for use with 
pipes. See https://3v4l.org/R5b2f/rfc#vgit.master:

     function assign_to(&$var) {
         return function ($value) use (&$var) {
             $var = $value;
         };
     }

     $string = "Hello World!";

     $string
         |> strtolower(...)
         |> ucfirst(...)
         |> assign_to($result);

     var_dump($result);
