Just messing around with some of the chapter exercises, I got an interesting result with concat that I don’t quite understand:
-- the example in the book, we're taking a two lists wrapped in
-- a list and flattening them into one
> concat [[1,2,3], [4,5,6]]
[1,2,3,4,5,6]
-- I figured that wrapping the two lists in parens would blow up,
-- but it gave me this! Curious...
> concat ([1,2,3], [4,5,6])
[4,5,6]hehe indeed! We’ll find out why when we get to type classes 
[Spoiler: class instances for tuples — parens with commas, like (1, 2) — can be somewhat counterintuitive]
Also, to clear up some syntax: the form foo (a, b) doesn’t call foo with arguments a and b, as you’d expect coming from other languages. (a, b) is a tuple, and the tuple is passed as an argument to foo
