The problem is when you want to write a large body of code that just *uses* lots of features (including syntactic features), *without* checking for them. Steve's examples were of how to support earlier versions, not how *not* to. At some point you want to just write Python 3 code and say to hell with Python 2, or the same for any particular version of Python 3. -- https://mail.python.org/mailman/listinfo/python-list
