As far as I am aware, there's nothing magical in the classes namedtuple creates that would require a custom metaclass - it's just that what it does would likely be even harder to read if written out explicitly rather than letting the compiler & eval loop deal with it. However, we've drifted off topic for python-dev at this point. If anyone wanted to experiment with alternative implementations, python-ideas would be the place to discuss that. Cheers, Nick.
