If you make it strict on the (,), like:

Things will get worst.
Well, that's what I expected, the elements of the list will b reduced to
head normal form,
I'd say that's because in the second case you also got to apply the (,),
besides the (+)/(-) constructor during the transversing...
Am I right?
opss... I meant to write: the (,) constructor besides the (+)/(-)...
