I disagree. "Pythonic" and "Unpythonic" are inherently subjective and are always used as an expression of opinion regarding the consistency of some code, routine or library in relation to the larger body of Python.

Unless it is written PEP8 or by Guido, I would never take a "pythonicism" to be nothing more than short-hand for "I think this is (in)consistent with the larger patterns and traditions of Python as I understand them."
