This can performed as a linked list of affected ranges. -- "Of all tyrannies a tyranny sincerely exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies, The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for own good will torment us without end, for they do so with the approval of their own conscience." - C.S.
