[4.2] Make "findClosure" Actually Find Closures

[mrofi]

Return of method findClosure() is Closure Object that is callable and must be an object. So only using is_callable() function isn't enough. A string could be callable, example when you adding alias 'app' in your route.
Route::get('apps', array('as' => 'app', function()
{
//
})); will make an error.

Good catch (this has been like this for ages) but why not just use $value instanceof Closure.

[mrofi]

Roger that, Mr. JoostK
Thank you. I have changed it.

[JoostK]

You can further simplify it to just return $value instanceof Closure; (and use Closure; at the top of the file), because is_callable on a closure always returns true.

[mrofi]

Sorry, I just a newbie and try to make this working out. Once again thank you Mr. JoostK

It should just be findCallable then.
