Hello folks,
Im kinda new to haskell. Ive only been fiddling around with it for bout 3 - 4 weeks now. And for the life of me... i cant seem to figure out why this doesnt work :
class Foo a where fooFunc :: a -> Int
data FooData = FData
instance Foo FooData where fooFunc _ = 10
class Bar a where barFunc :: (Foo b) => a -> b -> Int
data BarData = BData
instance Bar BarData where barFunc _ FData = 20
Ooo, ooo, I know this one, it's... oh, wait, I've been at work all day, so by now 30 other people have already replied. Heh. I need to find another day job... ;-)
