        //
        // 1) wrap the string in quotes
        //
        // 2) double-up quotes - i.e. " => ""
        //
        //    this is different from the libuv quoting rules. libuv replaces " with \", which unfortunately
        //    doesn't work well with a cmd.exe command line.
        //
        //    note, replacing " with "" also works well if the arg is passed to a downstream .NET console app.
        //    for example, the command line:
        //          foo.exe "myarg:""my val"""
        //    is parsed by a .NET console app into an arg array:
        //          [ "myarg:\"my val\"" ]
        //    which is the same end result when applying libuv quoting rules. although the actual
        //    command line from libuv quoting rules would look like:
        //          foo.exe "myarg:\"my val\""
        //
        // 3) double-up slashes that precede a quote,
        //    e.g.  hello \world    => "hello \world"
        //          hello\"world    => "hello\\""world"
        //          hello\\"world   => "hello\\\\""world"
        //          hello world\    => "hello world\\"
        //
        //    technically this is not required for a cmd.exe command line, or the batch argument parser.
        //    the reasons for including this as a .cmd quoting rule are:
        //
        //    a) this is optimized for the scenario where the argument is passed from the .cmd file to an
        //       external program. many programs (e.g. .NET console apps) rely on the slash-doubling rule.
        //
        //    b) it's what we've been doing previously (by deferring to node default behavior) and we
        //       haven't heard any complaints about that aspect.
        //
        // note, a weakness of the quoting rules chosen here, is that % is not escaped. in fact, % cannot be
        // escaped when used on the command line directly - even though within a .cmd file % can be escaped
        // by using %%.
        //
        // the saving grace is, on the command line, %var% is left as-is if var is not defined. this contrasts
        // the line parsing rules within a .cmd file, where if var is not defined it is replaced with nothing.
        //
        // one option that was explored was replacing % with ^% - i.e. %var% => ^%var^%. this hack would
        // often work, since it is unlikely that var^ would exist, and the ^ character is removed when the
        // variable is used. the problem, however, is that ^ is not removed when %* is used to pass the args
        // to an external program.
        //
        // an unexplored potential solution for the % escaping problem, is to create a wrapper .cmd file.
        // % can be escaped within a .cmd file.

    /**
     * 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:
     * `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:
     * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
     * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,

 *     - `key?: Token | null` – Set for pair values. May then be `null`, if

 *     - `value?: Token` – The value of a sequence item, or of a map pair.
 *   - `path`: The steps from the root to the current node, as an array of

 *   - `undefined` (default): Do nothing and continue
