Comment:

 GHC doesn't claim to implement full-laziness, although the documentation
 is a little vague on this point.  I've expanded it a bit now.

 Full-laziness is an optimisation that is performed when -O is on (and
 hence ''never'' when using GHCi).  Even so, it isn't applied consistently,
 so you shouldn't rely on GHC performing full-laziness.
