The question was: Is there an easy way of performing operations on arrays or lists without defining loops? The answer is: no, not really. Functions don't automatically thread themselves over lists. List comprehensions and maps provide a simple way to loop over a set, though. Personally, I think it's generally a good thing that functions don't automatically thread themselves over lists.
