[Haskell-beginners] Understanding syntax problems

[aditya siram]

A "type" can be both a synonym for both another type or a function. For example:

type ProcessIntList = [Int] -> [Int]

add_one :: ProcessIntList
add_one = map ((+) 1)

is the same as:
add_one :: [Int] -> [Int]
add_one = map ((+) 1)
