# It somehow looks as if overwriting property writers in the remixee class works, whereas overwriting # property readers doesn’t. All works well if the overwriting methods are def’d in the enhance block in the # remixer class (including a module doesn’t work either). However, this is rather undesireable since it means # that the code cannot be shared among different remixers.
