It occurred to me that I should clarify this statement, as it the obvious reading could be misleading. More precisely, that you register undos with the notion of how they need to be undone. Undo will always perform actions in the *reverse* order that they are registered, so you want to make sure that the registered actions can e correctly performed in the reverse order.
