I really like this as a general solution to a problem that bothers me
occasionally. IMHO it's much better than having UndoFiles or similar

The most direct way would be to go to Python at sourceforge[1] and make
a feature request to add peek to itertools. (This is probably the most
reasonable location for it.) Reque
