I see the problem now. But I am confused as to why there are no Bool class (like Num, Fractional...) in Haskell. If I had such a class then the problem is solved, (by making the "pm a" an instance of it) right? Or are there still more issues that I am not seeing?
Sorry, I gave a bad example. Here are two more general symptoms of direct style: being able to write something like f (if flip 0.3 then LT else EQ) where f is an existing function that takes an Ordering argument, and even being able to write something like and (map flip [0.3, 0.5]) where and :: [Bool] -> Bool map :: (a -> b) -> [a] -> [b] are existing functions. -- Edit this signature at http://www.digitas.harvard.edu/cgi-bin/ken/sig 1st graffitiist: QUESTION AUTHORITY! 2nd graffitiist: Why?
