Ah, you have a recursive query operator now. Interesting. Has working on this operator produced any insights for you? I'm thinking about this sort of thing right now as well. My post about 3 different kinds of trees is part of that same line of thought.

Heh. Some non-truths go through the same process, though. Viz. XML. Currently in the "accepted as self-evident" phase. I like to believe there's a "what was I thinking?!" phase that comes after. :-)
