Given the following function definitions:

var curry = function (f) {
               return function (x) {
                  return function (y) { return f(x,y); };
               };
};
var compose = function (f,g) {
                  return function (x) {
                     return f(g(x));
                  };
};
functionDef

what is the value of the following function call?
functionCall

Note that, if the function call generates an exception, the correct answer is the word "error" (without the double quotes) in all lowercase letters. Otherwise, the answer may be an integer or one of the Boolean constants true or false.
