         * Creates a `lodash` object which wraps `value` to enable implicit method
         * chain sequences. 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 chain sequences, which must be unwrapped with `_#value`, 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 and 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:

         * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
         * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
         *
