the proposal is to extend `bytes.__format__`
Currently bytes just inherits object.__format__
bytes.__format__.__qualname__

object.__format__ does not allow a non-empty format string.
'a{}b'.format(b'c\xdd')
"ab'c\xdd'b"
'a{:a}b'.format(b'c\xdd')
Traceback (most recent call last): File "<pyshell#26>", line 1, in <module> 'a{:a}b'.format(b'c\xdd') TypeError: non-empty format string passed to object.__format__
in some way that I don't think is entirely decided yet, but it would look something like this:
u'Hello, {:a}'.format(some_bytes_var) --> u'Hello, <whatever>'
Or:
u'Hello, {:#x}'.format(some_bytes_var) --> u'Hello, \x2d\x78\x68\x61...'
