Dear Haskell supporters, I have a some question about the definitions in haskell. 1. What is the use of making definitions compared to having no definitions? Is it just like a comment for documation or does it really make a difference in compiling the code? 2. What does the arrow(->) mean in such a definition? Is it a binary operation as *, +, -, <,>,= or is it something else? For example there is sumWithL :: [Int] -> Int -> Int Does this mean in other words [Int]+Int=Int 1. Why do we use clinches in such definitions. I concluded you need clinches if a function is not associative such as (a-b)+c . (Int->Int)->Int->Int But also if a higher order function needs more than one argument. (a->b)->c . Can you please explain it ? Thank you Kind regards.
