It's not ideal, because the resulting r-o property has no docstring:

class ex(object): ... @property ... def amp(self): ... ''' a nice docstring ''' ... return 23 ... ex.amp.doc class xe(object): ... def amp(self): return 23 ... amp=property(amp, doc='whatever!') ... xe.amp.doc 'whatever!'

Maybe we could fix that by having property(getfunc) use getfunc.doc as the doc of the resulting property object (easily overridable in more normal property usage by the doc= argument, which, I feel, should almost invariably be there).
