pseudo_class B(adds_to C):
def some_new_method():
...
B here is not a class, rather it is just a construction for grouping
together a set of extensions to an existing class.
The specific case in which I want to do this is with the Text
and ScrolledText classes in tkinter. At present we have
ScrolledText < Text
and I want to add some new functionality to both ScrolledText and
Text. So I want something like this,
ScrolledText < ExtendedScrolledText < ExtendedText < Text
where the Extended classes implement the new functionality. BUT
using sub-classing like this would mean that I would have to edit
or copy the tkinter library code, and I do not want to do this.
