The main argument I could see for holding off is that whenever it is we get to ADTs, we may want a more complex default implementation. But that would still presumably allow being overridden, like any other class, so it doesn't seem like a landmine to me. This doesn't have the same semantic issues that __toString() has (and have been discussed elsewhere). --Larry Garfield
