But I will mention the options that skip the __future__imports for those that choose not to use them (or have already done thework of using the u prefix in their code). Plus that doc probably will needan update of caveats that seem to bit everyone (e.g. the str(bytes) thingwhich I didn't know about) when trying to do source-compatible versions.-------------- next part --------------An HTML attachment was scrubbed...URL: <http://mail.python.org/pipermail/python-dev/attachments/20120228/6e6b5710/attachment-0001.html>
