+ * Wraps a function of any arity (including nullary) in a function that accepts

+ * @category Function
+ * @sig (* -> c) -> (a, b -> c)
+ * @param {Function} fn The function to wrap.
+ * @return {Function} A new function wrapping `fn`. The new function is guaranteed to be of
+ *         arity 2.
+ * @see R.nAry, R.unary
+ * @example
+ *
+ *      const takesThreeArgs = function(a, b, c) {
+ *        return [a, b, c];
+ *      };
+ *      takesThreeArgs.length; //=> 3
+ *      takesThreeArgs(1, 2, 3); //=> [1, 2, 3]
+ *
+ *      const takesTwoArgs = R.binary(takesThreeArgs);
+ *      takesTwoArgs.length; //=> 2
+ *      // Only 2 arguments are passed to the wrapped function
+ *      takesTwoArgs(1, 2, 3); //=> [1, 2, undefined]
+ * @symb R.binary(f)(a, b, c) = f(a, b)
