I would hope it could use whatever mechanism is already used for other conditions in the decimal module such as Underflow, Inexact, Rounded etc. But I have to admit I don't know exactly what those do. It appears they can either raise an exception or call a handle() method on the given exception. Are you thinking of putting the warn() call inside that handle() method? -- --Guido van Rossum (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
