| * Creates a function that invokes `func` with `partial` arguments prepended |
| * to those provided to the new function. This method is like `_.bind` except |
| * it does **not** alter the `this` binding. |
| * |
| * The `_.partial.placeholder` value, which defaults to `_` in monolithic |
| * builds, may be used as a placeholder for partially applied arguments. |
| * |
| * **Note:** This method does not set the "length" property of partially |
| * applied functions. |
