Damned if I can think of anything. Iota/range is important because indexing,
but nobody indexes things with rational numbers.

There is no real going back.  Though I may come to the Shire, it will
not seem the same; for I shall not be the same.  I am wounded with
knife, sting, and tooth, and a long burden.  Where shall I find rest?
