keepStable is a template function that simply wraps the range in a

Would these be composable? I.e.:
thisAttribute(thatAttribute(T)) is the same as
thatAttribute(thisAttribute(T)) ? Would the algorithm detect the 'inner'
attribute?
Great question. Not sure whether I can implement composition to be
entirely order-invariant, but yes, the algorithm should "see" various
attributes of the wrapped range.
