Multi-level undo in inform?

I'm having a hard time finding the answer to this via google... has anyone ever implemented a multi-level undo capability in inform? All of the games I can think of that use inform have the "sorry, can't undo two turns in a row" problem. I really like the nearly unlimited undo capabilities that TADS has, but even a two or three turn memory should be enough for those cases where somebody might take an action and then need to type "look" or something to figure out that they did the wrong thing.
