*A* reference is not sufficient. It has to be a reference which all other references agree with. I'll be kind, and lower the requirement to one where *the majority* of other references agree. The OP still won't find one :-) Or perhaps that should be a sad face smiley :-( How much time we would all save if academics and language designers would only stick to a single consistent terminology across all languages. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
