+ * 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`

+ * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
+ * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
+ *
+ * The chainable wrapper methods are:
+ * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
