-   * may be enabled using `_.chain`. The execution of chained methods is lazy,
-   * that is, execution is deferred until `_#value` is implicitly or explicitly
-   * called.
-   *
-   * Lazy evaluation allows several methods to support shortcut fusion. Shortcut
-   * fusion is an optimization that merges iteratees to avoid creating intermediate
-   * arrays and reduce the number of iteratee executions.
-   *
-   * Chaining is supported in custom builds as long as the `_#value` method is
-   * directly or indirectly included in the build.
-   *
-   * In addition to lodash methods, wrappers have `Array` and `String` methods.
-   *
-   * The wrapper `Array` methods are:
-   * `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`,
-   * `splice`, and `unshift`
-   *
-   * The wrapper `String` methods are:
-   * `replace` and `split`
-   *
-   * The wrapper methods that support shortcut fusion are:
-   * `compact`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `filter`,
-   * `first`, `initial`, `last`, `map`, `pluck`, `reject`, `rest`, `reverse`,
-   * `slice`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `toArray`,
-   * and `where`
-   *
-   * The chainable wrapper methods are:
-   * `after`, `ary`, `assign`, `at`, `before`, `bind`, `bindAll`, `bindKey`,
-   * `callback`, `chain`, `chunk`, `commit`, `compact`, `concat`, `constant`,
-   * `countBy`, `create`, `curry`, `debounce`, `defaults`, `defer`, `delay`,
-   * `difference`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `fill`,
-   * `filter`, `flatten`, `flattenDeep`, `flow`, `flowRight`, `forEach`,
-   * `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`, `functions`,
-   * `groupBy`, `indexBy`, `initial`, `intersection`, `invert`, `invoke`, `keys`,
