I don't think it's so clear cut. Stepanov's "Elements of Programming" lays
out a pretty clear (and familiar to many Haskellers) path through the
algebraic thicket of types, classes, and their properties, albeit in the
much clunkier setting of C++ and traits. The disadvantage to this approach
is substantial: just as with the from-principles approaches to redoing
Haskell's numeric hierarchy, you end up with a fearsome and complex set of
typeclasses that are difficult to learn and follow.
