Reading this thread, it occurs to me that I've probably never used a
lazy pattern in my code.  So if you, in spite of the helpful replies
you've got, still have problems understanding lazy patterns, it may be
an option to simply skip this part of the tutorial for now.

(Not that I recommend learning Haskell half-way, mind you, but it did
work for me :-)

If I haven't seen further, it is by standing in the footprints of giants
