Ok. >> Also, consider what >> "problem" you are trying to solve here. What is the benefit to the >> user of moving this error to compile time?

That's my point though, which you seem to be ignoring: if the user explicitly writes "1/0" it is not likely to be a bug. That's very different than "1/x" where x happens to take on zero at runtime -- *that* is likely bug, but a constant folder can't detect that (at least not for Python). -- --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
