Thanks for writing this PEP. Blessing one implementation for the stdlib and one official backport will make programmers’ lives a bit easier :)>>> @fun.register(int) ... def _(arg, verbose=False): ... if verbose: ... print("Strength in numbers, eh?", end=" ") ... print(arg) ...Does this work if the implementation function is called like the first decorated function? (I don’t know the proper terminology) e.g. >>> @fun.register(int) ... def fun(arg, verbose=False): ... if verbose: ... print("Strength in numbers, eh?", end=" ") ... print(arg) The precedent is 2.6+ properties, where prop.setter mutates and returns the property object, which then overwrites the previous name in the class dictionary.
Actually, properties return new instances: --> class Test(object): ... _temp = 'fleeting' ... @property ... def temp(self): ... return self._temp ... @temp.setter ... def new_temp(self, value): ... self._temp = value ... --> id(Test.temp) 30245384 --> id(Test.new_temp) 30246352 --> Test.temp is Test.new_temp False -- ~Ethan~ _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
