I'm still not convinced that we can simply drop the existing
immutable 8-bit string type and replace it with a mutable
bytes or buffer type, e.g. would buffer.lower() work on the
buffer itself or return a lowered copy ?

However, if that's where Python will be heading, then you're
right (for most of the codecs: some might want to return
Unicode objects, e.g. unicode-escape).
