  		 * ## Best practices
  		 *
  		 * Since the position of overwriting tokens (token in `redef` that overwrite tokens in the copied language)
  		 * doesn't matter, they can technically be in any order. However, this can be confusing to others that trying to

  		 * @param {Grammar} redef The new tokens to append.

  		 * @public

  		 *     // Prism.languages.css already has a 'comment' token, so this token will overwrite CSS' 'comment' token
  		 *     // at its original position
  		 *     'comment': { ... },
  		 *     // CSS doesn't have a 'color' token, so this token will be appended
  		 *     'color': /\b(?:red|green|blue)\b/

  		/**
  		 * Inserts tokens _before_ another token in a language definition or any other grammar.
  		 *
  		 * ## Usage
  		 *
  		 * This helper method makes it easy to modify existing languages. For example, the CSS language definition
  		 * not only defines CSS highlighting for CSS documents, but also needs to define highlighting for CSS embedded
  		 * in HTML through `<style>` elements. To do this, it needs to modify `Prism.languages.markup` and add the
  		 * appropriate tokens. However, `Prism.languages.markup` is a regular JavaScript object literal, so if you do
  		 * this:
  		 *
  		 * ```js
  		 * Prism.languages.markup.style = {
  		 *     // token
  		 * };
  		 * ```
  		 *
  		 * then the `style` token will be added (and processed) at the end. `insertBefore` allows you to insert tokens
  		 * before existing tokens. For the CSS example above, you would use it like this:
  		 *
  		 * ```js
  		 * Prism.languages.insertBefore('markup', 'cdata', {
  		 *     'style': {
  		 *         // token
  		 *     }
  		 * });
  		 * ```
  		 *
  		 * ## Special cases
  		 *
  		 * If the grammars of `inside` and `insert` have tokens with the same name, the tokens in `inside`'s grammar
  		 * will be ignored.
  		 *
  		 * This behavior can be used to insert tokens after `before`:
  		 *
  		 * ```js
  		 * Prism.languages.insertBefore('markup', 'comment', {
  		 *     'comment': Prism.languages.markup.comment,
  		 *     // tokens after 'comment'
  		 * });
  		 * ```
  		 *
  		 * ## Limitations
  		 *
  		 * The main problem `insertBefore` has to solve is iteration order. Since ES2015, the iteration order for object
  		 * properties is guaranteed to be the insertion order (except for integer keys) but some browsers behave
  		 * differently when keys are deleted and re-inserted. So `insertBefore` can't be implemented by temporarily
  		 * deleting properties which is necessary to insert at arbitrary positions.
  		 *
  		 * To solve this problem, `insertBefore` doesn't actually insert the given tokens into the target object.
  		 * Instead, it will create a new object and replace all references to the target object with the new one. This
  		 * can be done without temporarily deleting properties, so the iteration order is well-defined.
  		 *
  		 * However, only references that can be reached from `Prism.languages` or `insert` will be replaced. I.e. if
  		 * you hold the target object in a variable, then the value of the variable will not change.
  		 *
  		 * ```js
  		 * var oldMarkup = Prism.languages.markup;
  		 * var newMarkup = Prism.languages.insertBefore('markup', 'comment', { ... });
  		 *
  		 * assert(oldMarkup !== Prism.languages.markup);
  		 * assert(newMarkup === Prism.languages.markup);
  		 * ```
  		 *
  		 * @param {string} inside The property of `root` (e.g. a language id in `Prism.languages`) that contains the
  		 * object to be modified.
  		 * @param {string} before The key to insert before.
  		 * @param {Grammar} insert An object containing the key-value pairs to be inserted.
  		 * @param {Object<string, any>} [root] The object containing `inside`, i.e. the object that contains the
  		 * object to be modified.
