If I remember the sequence of events correctly, I thought of
map(bytes.byte, data) first, and then Guido suggested a dedicated
iterbytes() method later.

The step I hadn't taken (until now) was realising that the new
memoryview(data).iterbytes() capability actually combines with the existing
(bytes([b]) for b in data) to make the original bytes.byte idea unnecessary.

Nick.
