  8. * Creates a function that invokes `func` with `partials` prepended to the
  9. * arguments it receives. This method is like `_.bind` except it does **not**
  10. * alter the `this` binding.
  11. *
  12. * The `_.partial.placeholder` value, which defaults to `_` in monolithic
  13. * builds, may be used as a placeholder for partially applied arguments.
  14. *
  15. * **Note:** This method doesn't set the "length" property of partially
  16. * applied functions.
