A minuscule nit: the rot13 codec has no library equivalent, so it won't be supported anymore :) Given that there are valid use cases for bytes-to-bytes translations, and a common API for them would be nice, does it make sense to have an additional category of codec that is invoked via specific recoding methods on bytes objects? For example:
encoded = data.encode_bytes('bz2') decoded = encoded.decode_bytes('bz2') assert data == decoded
This is exactly what I proposed a while before under the name bytes.transform().
IMO it would make a common use pattern much more convenient and should be given thought.
If a PEP is called for, I'd be happy to at least co-author it.
Codecs are a major exception to Guido's law: Never have a parameter whose value switches between completely unrelated algorithms. Why don't we put all string transformation functions into a common module (the string module might be a good place):
import string string.rot13('abc')
