Robert Kern:This is similar to implementing "Undo" functionality in applications.<In a quite-high-level language (like Python, but not necessarily in Python itself) it may become eventually advantageous to add some (even limited) built-in form of undo.
Right now, I believe, one could develop an undo module with undolist and undodict classes that wrap instance mutations with an append to an undoinfo list.
