Hi,

Three weeks ago, I posted a draft on my PEP on this mailing list. I tried to include all remarks you made, and the PEP is now online: http://www.python.org/dev/peps/pep-0400/ It's now unclear to me if the PEP will be accepted or rejected. I don't know what to do to move forward. I asked Guido in private, but I didn't get any answer. Victor

Sorry Victor, I somehow didn't see that message even though I received it (I probably thought it was a continuation of the python-dev thread which I've been ignoring).

Unfortunately I don't have time to go back and read the whole thread. I think I haven't used codecs.StreamReader/Writer myself, and I don't think I've seen much use of them either (which doesn't mean there isn't). My gut feeling is that yes, they should eventually go away, but no, there's no particular hurry, and no, I don't think you should change codecs.open() to call io.open().

I think the best thing is to campaign (e.g. in docs) for people to stop using codecs.open/StreamReader/Writer and start deprecating them formally once we feel that most users have switched. It's possible that that could happen before 3.3 is released, but I'm kind of doubtful about that myself.

Sorry again for missing your private emails!
