I'm having trouble with blade and the Request class from lumen. To change the class of a menu item I'm calling the 'is' method of the 'Request' class like this:

`{{ Request::is('thepage/*') ? 'class="active"' : '' }}`

Sadly everytime I open the page it results in 

> 
> PHP Fatal error: Class 'Request' not found in /.../storage/framework/views/...
> 
> 
> 

I really don't understand why that happens.
