Sounds like you could use ZPatterns.I perhaps should have clarified that I need to be able to specify the name of the attributes or methods at run time, so ComputedAttribute unfortunately won't do the trick as you have to define each attribute/method you require in the class definition.ie. I need something like : def __getattr__(self,attr): if name in self.methodlist: <do something> return Implicit.__class__.__getattr__(self,attr) where self.methodlist is a list of strings that may change per instance and/or at runtime, or itself could be calculated at the time of doing the __getattr__ (eg self.getMethodList()).
If you do implement your own __getattr__, you might need to check if the object you want to return implements __of__, and return object.__of__(self) (or something like that).
