The hex() method isn't implemented yet, but a really simple
listcomp/gencomp already gives the 'list of integers' format:
>>> data = b"what's in a name?"
>>> repr(data)
"b'what\\'s in a name?'"
>>> [x for x in data]
[119, 104, 97, 116, 39, 115, 32, 105, 110, 32, 97, 32, 110, 97, 109,
101, 63]
Given the simplicity of retrieving the underlying integers, I think the
string representation makes a good default repr implementation.
Cheers,
Nick.
