[Haskell-cafe] funct.prog. vs logic prog., practical Haskell

I would have thought that a major motivation for the study of haskell,or for 
that matter ML, Clean, would be their type systems: statically typed higher 
order parametric polymorphism which is certainlly different enough from that 
of prolog to warrant study. So from the perspective of type systems and 
associated gaurantees functional programming languages probably represent 
the best environment in which to study these concepts.
