Now the question is, could that restriction be lifted, i.e., would it be
possible/worthwhile to let defaulting also take place if user defined classes
are involved?
The current defaulting mechanism in Haskell is very, very conservative.
You could easily relax the restriction that all classes have to come
from the Prelude. I have sometimes wished for that.
But on the other hand, I try to avoid relying on defaulting anywhere,
so it doesn't disturb me much.
