Yes, which is why you could include a 2.X and people who target, say current +/- 0.1 can choose their poison. > But my main reason for not wanting to do this is that the document is > aimed at people who want to write Python 3, not to encourage people to > stick with 2:-) I actually think that it is the other way round. People should get familiar with py3 features even if they are not yet ready to "abandon" py2 (yet). I also think that using some of the backported/supported features might spur interest in features that are 'py3 only' and therefore encourage the adoption of py3. It would also be nice to have a summary of things people can do *now* if they want to keep the changes from 2to3 to a minimum, which will be with us for some time. But that is not something *you* have to write .. :-) -- .''`. Wolodja Wentland <wentl...@cl.uni-heidelberg.de> : :' : `. `'` 4096R/CAF14EFC `- 081C B7CD FF04 2BA9 94EA 36B2 8B7F 7D30 CAF1 4EFC
