I think it would be more "sexy" to serve files from controller easier (like `json()` helper does).
**This Controller helper allows user to serve files to Response in these ways:**
* pass `Symfony\Component\HttpFoundation\File` (or `Symfony\Component\HttpFoundation\UploadedFile`) instance
* [REMOVED] provide content as `string` and specify file name (mime type will be auto recognized)
* provide path to file (you are still able to specify other than original file name)
**Examples**
return $this->file($uploadedFile);
// ...or...
return $this->file('/path/to/my/picture.jpg');
