This is an interesting idea, but I wonder if it wouldn't be more effective if you used the string repr instead: body = repr(self.serialize_body()). How do you feel about that?

[Kriechi]

Usually I'm not interessted in the body of a data frame (mostly plain text anyway), but in one of the other frame types (headers, error codes, etc).

I think this is not very readable or intuitive to understand:

>>> repr(b"\x02\x10\x32\x41\x42\x43\x44")
"'\\x02\\x102ABCD'"

where as this is much better IMHO:

>>> b"\x02\x10\x32\x41\x42\x43\x44".encode('hex')
'02103241424344'

@Kriechi That's fair. In that case, you'll need to fix the test breakage. =)

Done.
