Of course, you'd probably do repr(M) instead, which is more standard Python. But that's not something I'd expect someone to be able to guess naturally. And I don't think using repr would work anyway, since that is what is used for output when you just type M. print M prints M.__str__() M by itself prints out M.__repr__() > A configuration object would be a nice thing to have.
