I have, and then, when I failed to subclass it, I considered doing 
aggregation, and make it behave byte-like. But how to implement the 
overridden __hash__ method? It will still require at least *some* 
redundant copying. And there is the slicing thing... the whole idea 
started to feel like I was performing tonsillectomy through the anal cavity.
