I'm just getting confused by the terminology. Those are pure functions too. And you have different functions because they're doing something completely different, operating on computational structures that are different from primitive values the 'normal' functions as you called them operate on. It's like saying C++/Java etc. are confusing because you can only print certain values, but you can't print the print statement.
