Currying subtraction
Solution 1:
You can use the subtract function instead of - if you want to right-section subtraction:
map (subtract 1) [1..5]
Solution 2:
Since - is both the infix subtract and the prefix negate, you can't use the (*x) (where * is an infix operator and x a value) syntax for -. Luckily Prelude comes with negate and subtract, which is \x -> -x and \x y -> y-x respectively, so that you may use those where you need to differentiate between the two.
