It would be great if someone could exemplify these "rules of thumb",

poor and I feel I can't make informed decisions on when I need to make
something more strict or lazy.

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...
