newbie syntax question

[Cagdas Ozgenc]

Hi,   I am extremely new to Haskell. This will be my first question, so go easy. I have just read Chapter 1 on Simon Thompson's book.   for example a function declaration is given as follows   scale : : Picture -> Int -> Picture     If the first two types are input variables why does the syntax require me to use arrows twice? I mean isn't the following syntax more readable (hypothetically)?   scale : : Picture , Int -> Picture     Is there a specific reason not to be able to distinguish the input parameters from the output parameter?   Thanks
