Is it really clear or obvious what

map . (+)

means?

Yes, it is perfectly obvious once you write it like this: incrEach :: Integer -> [Integer] -> [Integer] incrEach = map . (+) Now compare that to the following function, which does the some thing but without point-free notation: incrEach' :: Integer -> [Integer] -> [Integer] incrEach' i is = is >>= \i' -> return (i'+i) Which one is harder to read? ;-) Peter
