Well fine. I should have realised the question was just a pretense and that
there really never was any intention to consider the reactions, because
the answer is already fixed. Of course a key function can always be written,
it may just need a specific class to implement the specific order. Likewise
there is no reason to expect the order-functions to preform worse when
implemented in a class, rather than in a function.
