But Double is already quite badly behaved:
let x = 1e20 Prelude> 1 + (x - x) 1.0 Prelude> (1 + x) - x 0.0
Ewwww. Whilst that's understandable and unavoidable, that kindof rings alarm bells for folds of Doubles in an automatic threading situation. Ie, if we split our fold between 4 cores, we might get a different answer than if we split it between 8 cores?
