Is there a way to integrate a undo/redo system in an already existing app without a huge amount of recording to support it? I.e., converting to using commands. I'd like to specify what is going to be modified and what needs to be done to restore the state. Given D's strong meta capabilities, I wonder if much of this can be alleviated? A struct that monitors it's own changes and possibly designing something using reversible delegates.
