I think you should seperate the costs from the benefits. It is not because
the costs can be high there is little value.
And how do you count use cases? What about the following pattern:
while (a, b) := next_couple(a,b)[-1]:
Is that one use case or is that a use case for each kind of couple?
And even if the benefits are little per case, they can add up with every
occasion such a case pops up.
