With regard to Python 3's print statement, I don't understand it. Or rather, I don't understand why they changed only the print statement. If nothing else, raise and assert should have had the same treatment. And Python 3's unicode handling isn't sane. Or rather, it is saner internally, but not sane on the interface. I mean, recreating `cat` is bad enough. Python 3 made unicode handling slightly easier and byte handling gratuitously harder. But this is probably bikeshedding. Personally, the bigger problem is not creating a relatively frictionless upgrade path. If you can't run things on the new version without manual editing, you won't move over unless everything you depends on moves over. Catch-22. Python is slowly moving over, largely because a) it's not generally too difficult to port the code (and largely automated to boot), and b) you can relatively easily write code that works on both versions.
