can.List.sort method not available in can v2.2.1?

Hi,

trying to sort a can.Model.List returned by my Model.FindAll method, I was glad to discover in the api the can.List.sort method. But in my context, this method is not available.

Ex :

1. var list = new can.List(['item1','item2']);
   console.log(list.sort);
   
   > undefined
   

What am I doing wrong?

Thanks,

Thomas
