Actually, there's an almost throw-away mention in http://docs.python.org/ref/descriptor-invocation.html which gives you what you need (although not, I have to say, in an easily digestible form). What I've not seen documented anywhere is the: @property def fset(self, value): ... idiom. It's not obvious from the documentation of the property function that it can be used as a decorator like this.
