You should be able to replace it with something like:

   @do_something
   def content_size():
       return "Size of the content area."

Where do_something calls the function to get the string argument and takes
the name from the function.__name__ (and uses them to create and return the
overridable_property).

May you do good and not evil
May you find forgiveness for yourself and forgive others
May you share freely, never taking more than you give.
