Hello,
I am writing a function(actually much more than this):
bozo :: Char -> Char
bozo 0x02 = 'a'
...
However, I get complaints from ghc suggesting that I should add an "instance
declaration (Num, Char). I (mistaking) thought I understood the Haskell
class hierarchy and the associated constraints .. but apparently not .. =>
help please. Should
Kind regards, Vasya
