Practicality beats purity and all that.
Are you speaking on behalf of all authors of alternate implementations, or even of some of them? It certainly is not true that CPython's behaviour "is" the spec. PyPy keeps a list of CPython behaviour they don't match, either because they choose not to for other reasons, or because they believe that the CPython behaviour is buggy. I daresay IronPython and Jython have similar. And this especially applies when CPython explicitly states that certain behaviour is implementation-dependent and could change in the future. -- Steve _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
