@Guido

One would have to introduce some kind of convention where you can write properties with a leading

One doesn't even need the @property decorator in this case. For example:

def getattr(name): g = globals() name = '_' + name if name in g: return gname raise AttributeError(...)

def _attr(): "do something" return actual_object

One can even write a decorator that would change the name automatically (but this will require a call at the end of module to unbind original names). The space for play is infinite. The question is what exactly is needed. I would say that already basic customisation (like getattr) will be enough. IIUC, this will be actually a bit faster than setting class since only "customized" attributes will be affected.
