Hi,
You're pretty close, actually. In general, remember the following:
'type' introduces a type synonym, which means that you're just renaming an
existing type, not creating a new one. this means that you don't need
constructors.
'data' means that you're defining a new type; in order to do

Did you mean this to be a *list* of Assertions? e.g.
type Prolog = [Assertion]

Hi All,
I was trying to write go program in haskell - My code fragment looks
like this -
getBoardSize :: IO Bool
-- TODO : What could be the type of getBoardSize
getBoardSize = do c - getLine
validateBoardSize ( atoi c )
-- Convert a string to an integer.

atoi :: [Char] - Int
atoi (h : []) = if isDigit h then digitToInt h else 0
atoi (h : t) = if isDigit h then digitToInt h * ( 10 ^ length t) +
atoi t else 0
you can use
Thanks a ton Hal for the quick clarification. It worked .
Cheers
Karthik.

Hi Artie,
You are right . I had changed the code as follows -
run = do c - getBoardSize
validateBoardSize c
-- Get the board size as input
getBoardSize :: IO ( Int )
validateBoardSize :: Int - IO ()
... and follows.
run function is the entry point.
Thanks for the clever code Oleg. I've tried to extend it again to track
the types of methods as well as just the names, giving a functional
dependancy from the class, method, and to result type. I can't get the
overlapping instances to work out, so I'm handing it back to a master,
and the rest of
