+    /**
+     * Creates a `lodash` object which wraps `value` to enable implicit method
+     * chaining. Methods that operate on and return arrays, collections, and
+     * functions can be chained together. Methods that retrieve a single value or
+     * may return a primitive value will automatically end the chain sequence and
+     * return the unwrapped value. Otherwise, the value must be unwrapped with
+     * `_#value`.
+     *
+     * Explicit chaining, which must be unwrapped with `_#value` in all cases,
+     * may be enabled using `_.chain`.
+     *
+     * The execution of chained methods is lazy, that is, it's deferred until
+     * `_#value` is implicitly or explicitly called.
+     *
+     * Lazy evaluation allows several methods to support shortcut fusion. Shortcut
+     * fusion is an optimization to merge iteratee calls; this avoids the creation
+     * of intermediate arrays and can greatly reduce the number of iteratee executions.
+     * Sections of a chain sequence qualify for shortcut fusion if the section is
+     * applied to an array of at least two hundred elements and any iteratees
+     * accept only one argument. The heuristic for whether a section qualifies
+     * for shortcut fusion is subject to change.
+     *
+     * 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`, `shift`, `sort`, `splice`, and `unshift`
+     *
+     * The wrapper `String` methods are:
+     * `replace` and `split`
+     *
+     * The wrapper methods that support shortcut fusion are:
+     * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
+     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
+     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
+     *
+     * The chainable wrapper methods are:
