The motivation for this patch was to be able to chain together operator.itemgetter objects so that I could sort a list of items that have the form ((a,b), c) by the 'a' or 'b' part of the item.

Sorting by 'b' can be accomplished with:
l.sort(key=compose(itemgetter(1), itemgetter(0)))

compose(itemgetter(1), itemgetter(0)) is equivalent to

def c(v):
    return itemgetter(1)(itemgetter(0)(v))
