This Joni Mitchell lyric just popped into my head: "I've looked at clouds from both sides now
From up and down, and still somehow It's cloud illusions I recall I really don't know clouds at all"
A LOT of cool stuff here, but the learning curve is murder.

data (RealFloat a) => Complex a = !a :+ !a

Forcing; it means that the values are evaluated (up to WHNF) before the Complex value is constructed: http://www.haskell.org/ghc/docs/6.12.1/html/users_guide/bang-patterns.html -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
