Con: subclassing in general is a bad idea. Subclassing Deferred is an even worse idea. What if Deferred one day gets a new method called 'call' that does something different? Your code would all break. > Anything why I shouldn't do? Providing three different ways to do the same thing just so that you can use different syntax depending on your mood is a recipe for making your code hard to read. Pick one style, stick to it as much as possible - consistency is more important than the benefits of any one particular style :). (Except the subclassing one. Don't do that.) -glyph
