 /**
  * Gets a WordPress® post by path; instead of by ID.
  *
  * @param string $path A URL path (ex: `/sample-page/`, `/sample-page`, `sample-page`).
  *    This also works with sub-pages (ex: `/parent-page/sub-page/`).
  *    Also with post type prefixes (ex: `/post/hello-world/`).
  *    Also with pagination (ex: `/post/hello-world/page/2`).
  *
  * @param array  $exclude_types Optional. Defaults to `array('revision', 'nav_menu_item')`.
  *    We will NOT search for these post types. Pass an empty array to search all post types.
  *    Important to note... it is NOT possible to exclude the `attachment` type;
  *    because {@link \get_page_by_path()} always searches this type.
  *
  * @return null|\WP_Post A WP_Post object instance if found; else NULL.
  *
  * @throws exception If invalid types are passed through arguments list.
  *
  * @see http://codex.wordpress.org/Function_Reference/get_page_by_path
  *    NOTE: This supports MORE than just pages; even though the function name implies otherwise.
