Well, it surprises me.  I thought the FFI preserved the distinction  
between an object and a pointer to an object, otherwise why  
distinguish between (:struct foo) and (:* (:struct foo)) as foreign  
types?  (Feel free to treat that as a rhetorical question.  I know  
you've got more important things to do.)

Thanks for the explanation!
