I've done things like this before, and I would say the Kernigan quote is not appropriate here, and the implication that isn't not simple and robust is incorrect. It's repetitive code like the OP posted that's complex and flimsy. Repetitive code is the exact opposite of the DRY principle, and there's a reason DRY is one of the most often cited principles here. Using advanced techniques like metaclasses to exploit the similarity to reduce or eliminate the repetitiveness can, if done well, simplify code. By a lot. Advanced is not the same thing as complex. In this particular case I'd say the recommendation to do something else is a good one, but it's not true in general. Carl Banks -- http://mail.python.org/mailman/listinfo/python-list
