But aren't all classes callable? But you are referring to the initial values of the items, but still, why should those be restricted from being any general object? Not being _functions_ is probably OK, but I'm not sure how strong the distinction is between functions and classes, regarding being callable... So objects are only callable if the class contains a def __call__, but still, that seems quite restrictive.On Fri, Apr 26, 2013 at 12:38 PM, Guido van Rossum <[email protected]> wrote:If the above syntax won't work, that isinstance() outcome isn't really important. :-(Can't we do some kind of callable check? There may be some weird decorators that won't work, but they aren't likely to be useful in this context.Yeah, it may not be as tricky as I feared: adding "not callable(attr_val)" to the conditions for deciding whether or not to convert a class attribute to an instance of the enum would likely suffice to address the method problem. You couldn't create an enum of callables, but that would be a seriously weird thing to do anyway....
