I know how facades work and I can find full facade list in Laravel:
<https://laravel.com/api/5.2/Illuminate/Support/Facades.html>

But how I can see all available functions for each facade?

If I use the `Session` Facade I can:

1. Find methods in laravel documentation --
<https://laravel.com/docs/5.2/session>
2. Search methods in each class in the `Illuminate/Session` namespace --<https://laravel.com/api/5.2/Illuminate/Session.html>

Is there a more elegant way to find the available functions?
