In a sense the lambda here is not unnamed; it's name is the name of the keyword argument, 'callback', which is indeed a poor name at in terms of self-documentation. I don't see how replacing the lambda with a (better) named function would be any better than using the same name as a keyword parameter. George -- http://mail.python.org/mailman/listinfo/python-list
