(snip code)


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.
