lookup('rot13') should fail with a lookup error to keep backward
compatibility. You can just change the default values to:
def lookup(encoding, decoded_format='text', encoded_format='binary'): ...
If you patch lookup, what about the following functions?
- getencoder()
- getdecoder()
- getincrementalencoder()
- getincrementaldecoder()
- getread()
- getwriter()
- itereencode()
