If I recall the trait discussion properly, traits are a compile-time 
thing.  Closure binding is a run-time thing.  They are not comparable 
and one cannot really be used to implement the other.  (Well, 
hypothetically bound closures could kinda-sorta replicate traits, but it 
would be a pretty lousy way of doing it as you get no compile-time 
enforcement or interface support.)
