[Haskell-cafe] what did I do wrong

[Corentin Dupont]

Hi,
remember that in Haskell argument application is just a space, not using
parenthesis and comma like in some imperative languages.
In Java: myFunc (a, b)
Is equivalent in Haskell to: myfunc a b
so center ((1,2), (3, 4)) is a function applied to only one arguement (a
tuple of tuples)
