I have a question about the cost of list comprehension and map function.

For example, I have a list of Double and I want to do lots of calculation on it. There are two ways to do that: 1. [x ** 3 | x <- list] 2. map (flip (**) 3) list I am wondering if the cost of using them could be very different and why.

List comprehensions are just syntatic sugar. You should expect both (1) and (2) to be exactly the same when compiling. Cheers, =) -- Felipe.
