Curried anonymous function in SML

Question

I have the function below and it works:

(fn x => x * 2) 2; 

but this one doesn\'t work:

(fn x y => x + y ) 2 3;
         


        

Answer 1

(fn x => fn y => x+y) 2 3; works. fn simply doesn't have the same syntactic sugar to define curried functions that fun has.
