[Haskell-cafe] Self Study with SOE

I have been steadily working through Haskell SOE. However, as the exercises
become more involved, I would like to know, not only that the answer I come
up with works, but that I am doing it the right way (the elegant way?).
For instance, Chapter 8 Exercise 8.3 requires me to modify the "area" and
"perimeter" functions to accept negative arguments. My solution would be to
change the functions to take the absolute value of the arguments as they
come in. This would work but it doesn't seem all that elegant.
Additionally, SOE exercises do not come with test data so I can test
correctness. Is it part of my responsibililty as a student to come up with
test data (boundary conditions etc) as I try to answer the questions?
Is there some kind of solutions manual available? I promise I am not doing
this as homework for a course.
Find a local pizza place, music store, museum and more
then map the best
