When I first learned Haskell, lazyness sounded like a great idea, and I 
was somewhat puzzled as to why you would ever want to turn such a thing 
off. Fortunately (?!) after lots of experiments with the lambda calculus 
and other such things, I quickly realised that reducing large 
subexpression can sometimes be a big win. But I couldn't find much on 
the Wiki that explains all this stuff, and it would probably be quite 
useful to have!

Of course, now we need somebody to *write* the thing...
