- * Wraps a constructor function inside a curried function that can be called
- * with the same arguments and returns the same type. The arity of the function
- * returned is specified to allow using variadic constructor functions.
- *
- * @func
- * @memberOf R
- * @since v0.4.0
- * @category Function
- * @sig Number -> (* -> {*}) -> (* -> {*})
- * @param {Number} n The arity of the constructor function.
- * @param {Function} Fn The constructor function to wrap.
- * @return {Function} A wrapped, curried constructor function.
- * @example
- *
- * // Variadic Constructor function
- * function Salad() {
- * this.ingredients = arguments;
- * }
- *
- * Salad.prototype.recipe = function() {
- * const instructions = R.map(ingredient => 'Add a dollop of ' + ingredient, this.ingredients);
- * return R.join('\n', instructions);
- * };
- *
- * const ThreeLayerSalad = R.constructN(3, Salad);
- *
- * // Notice we no longer need the 'new' keyword, and the constructor is curried for 3 arguments.
- * const salad = ThreeLayerSalad('Mayonnaise')('Potato Chips')('Ketchup');
- *
- * console.log(salad.recipe());
- * // Add a dollop of Mayonnaise
- * // Add a dollop of Potato Chips
- * // Add a dollop of Ketchup
