But I really hope we as a community don't perpetuate the myth that you cannot port to Python 3 without this, and I hope that we spend as much effort on educating other Python developers on how to port to Python 3 right now supporting Python 2.6, 2.7, and 3.2. That's the message we should be spreading and we should be helping developers understand exactly how to do this effectively, among the many great options that exist today. Only in the most extreme cases or the most inertially challenged projects should we say "wait for Python 3.3".

Well, when the code is committed I will update the porting HOWTO and push the future imports first since they cover more versions of Python (i.e. Python 3.2). But I will mention the options that skip the future imports for those that choose not to use them (or have already done the work of using the u prefix in their code). Plus that doc probably will need an update of caveats that seem to bit everyone (e.g. the str(bytes) thing which I didn't know about) when trying to do source-compatible versions. -------------- next part -------------- An HTML attachment was scrubbed...
