You should look at the enthought.traits module. It does this and much more (and this is coded in C, so it is fast !)

Hmmm... I think I prefer the approach of inheriting from 'WithProperties' (a class that uses the '__properties__' metaclass) and then having proeprties created automatically from getter / setter methods.

I think this is much more readable than inline classes and avoids the settrace hacks.
