I do think my code (as posted) is "unnatural and ugly". Just an example, not even a class. I'd really love to figure out a proper model of parent-element relationship using metaclasses, etc. I tried very hard (several times) to find such a model, or at least "a cleaner user interface", and I played with some interesting ideas but cooked no cake. Maybe you have some cool ideas on how one can make this work (and appealing to others). > category) and category. Metaclasses are a good match for Categories. Also cool. I remember I was hit by the python version of a few of the paradoxes in early days set thery. YMMV.
