10 * This method is like `_.partial` except that partially applied arguments
11 * are appended to the arguments it receives.
12 *
13 * The `_.partialRight.placeholder` value, which defaults to `_` in monolithic
14 * builds, may be used as a placeholder for partially applied arguments.
15 *
16 * **Note:** This method doesn't set the "length" property of partially
17 * applied functions.
