[Python-ideas] Stop displaying elements of bytes objects as printable ASCII characters in CPython 3

[Cameron Simpson]

As someone who uses ASCII or more commonly UTF-8 byte sequences, I find the 
current ascii-ish default display handy. That said...

To my eye that is a single number expressed in base 16 and would
imply an endianness. I imagine you really mean a transcription of
the bytes in hex, with a leading 0x to indicate the transcription.
But it is not what my eye sees.

Of course, the natural transcription above implies big endianness, as is only 
right and proper:-)

Why not give bytes objects a .hex method, emitting bare hex with no leading
0x? That would be my first approach.

>b'Abc'.decode('hexescapes') --> '\x41\x62\x63'

OTOH, this is really neat. And .decode('hex') for the former?
