I never want to iterate, but I love slice syntax and indexing. Don't think you can have that w/o being able to loop over it can you? Maybe I'm just thinking slow since I just woke up.

But you'd have to decide if bytes/bytearray is a sequence of integers or a scaler... In fifteen years of Python programming, I have literally never wanted to iterate over 'str' (or now 'bytes'). I've always considered the fact that Python made them iterable by default (rather than e.g. defining a method / property to get to an iterable "view" on the underlying string) a wart and a serious bug magnet.
