Maybe, but I'd be dubious of making it that simplistic. For instance, which of these is more likely to be useless? spam or ham() spam() or ham Syntactically, both of them are 'or' expressions, but one of them is almost certainly unnecessary, while the other is just an oddly-written conditional statement and most definitely useful. In any case, this is the job of linters, NOT the language itself. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
