Laravel 5 - Using Class word as model name

I have a model called Class and User.

my User model has this line of code.

use App\Class;

its giving me an error "syntax error, unexpected 'Class' (T_CLASS), expecting identifier (T_STRING)"

but when I use other names its just fine. could someone tell me why its not possible to use the word Class as a classname
