Remember that properties have nothing magical - they're just one
possible (and very handy) way to use the descriptor protocol to
implement computed attributes. If you have to resort to any non-obvious
trick or just too much boilerplate code with properties, then it's
probably time to implementent your own custom descriptor object.
