The % operator already does too much guessing: if the string contains exactly one %-format, the argument may be either a size-1 tuple or a non-tuple, otherwise it has to be a size-N tuple, except if the %-formats use the %(name)X form, then the argument must always be a dict. It doesn't sound to me as if adding more guesswork is going to improve its reliability. -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
