What's wrong with b[i:i+1] ?
It always succeeds while indexing can trigger an IndexError.
Right. You want a method with the semantics of __getitem__() but that returns the desired type.
And if this is called __getitem__ (with slices delegated to bytes.__getitem__) and implemented in a class, one has a view. Maybe I'm missing something, but I fail to understand what makes this significantly more problematic than an iterator. Ok, I guess we might also need __len__.
