I agree that it would be good if Python would be clear about this error. I suggested as much on Python-Ideas a few months ago: https://groups.google.com/d/topic/python-ideas/dNbXlL2XoJ8/discussion or https://mail.python.org/pipermail/python-ideas/2016-January/038165.html The thread did not end with a strong opinion one way or the other, though it did get distracted by other kinds of import mistakes. --Ned.
