Multiple inheritence is often more trouble than it's worth. For example, you have a class foo that inherits from both class bar and class baz. Classes bar and baz both have a fubar() method. When you create a foo object and call its fubar() method, which fubar() method is called: bar's or baz's? It seems to me that using aggregate to glue one class's methods and data to another object is a bit like Ruby's fixins, but I could be wrong...
