     *   - mappings: A string of base64 VLQs which contain the actual mappings.
     *   - file: Optional. The generated file this source map is associated with.

     * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
     * input.
     *
     * The first parameter is a raw source map (either as a JSON string, or already
     * parsed to an object). According to the spec for indexed source maps, they
     * have the following attributes:
     *
     *   - version: Which version of the source map spec this map is following.
     *   - file: Optional. The generated file this source map is associated with.
     *   - sections: A list of section definitions.
     *
     * Each value under the "sections" field has two fields:
     *   - offset: The offset into the original specified at which this section
     *       begins to apply, defined as an object with a "line" and "column"
     *       field.
     *   - map: A source map definition. This source map could also be indexed,
     *       but doesn't have to be.
     *
     * Instead of the "map" field, it's also possible to have a "url" field
     * specifying a URL to retrieve a source map from, but that's currently
     * unsupported.
     *
     * Here's an example source map, taken from the source map spec[0], but
     * modified to omit a section which uses the "url" field.
     *
     *  {
     *    version : 3,
     *    file: "app.js",
     *    sections: [{
     *      offset: {line:100, column:10},
     *      map: {
     *        version : 3,
     *        file: "section.js",
     *        sources: ["foo.js", "bar.js"],
     *        names: ["src", "maps", "are", "fun"],
     *        mappings: "AAAA,E;;ABCDE;"
     *      }
     *    }],
     *  }
     *
     * The second parameter, if given, is a string whose value is the URL
     * at which the source map was found.  This URL is used to compute the
     * sources array.
     *

        //               Used as-is in ISO2022 family.

        //                0201-1976 Roman, 0208-1978, 0208-1983.
        //  * ISO2022-JP-1: Adds esc seq for 0212-1990.
        //  * ISO2022-JP-2: Adds esc seq for GB2313-1980, KSX1001-1992, ISO8859-1, ISO8859-7.

    // less.js - parser
    //
    //    A relatively straight-forward predictive parser.
    //    There is no tokenization/lexing stage, the input is parsed
    //    in one sweep.
    //
    //    To make the parser fast enough to run in the browser, several
    //    optimization had to be made:
    //
    //    - Matching and slicing on a huge input is often cause of slowdowns.
    //      The solution is to chunkify the input into smaller strings.
    //      The chunks are stored in the `chunks` var,
    //      `j` holds the current chunk index, and `currentPos` holds
    //      the index of the current chunk in relation to `input`.
    //      This gives us an almost 4x speed-up.
    //
    //    - In many cases, we don't need to match individual tokens;
    //      for example, if a value doesn't hold any variables, operations
    //      or dynamic references, the parser can effectively 'skip' it,
    //      treating it as a literal.
    //      An example would be '1px solid #000' - which evaluates to itself,
    //      we don't need to know what the individual components are.
    //      The drawback, of course is that you don't get the benefits of
    //      syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
    //      and a smaller speed-up in the code-gen.
    //
    //
    //    Token matching is done with the `$` function, which either takes
    //    a terminal string or regexp, or a non-terminal function to call.
    //    It also takes care of moving all the indices forwards.

            //
            //   Ruleset ->  Declaration -> Value -> Expression -> Entity
            //
            // Here's some Less code:
            //
            //    .class {
            //      color: #fff;
            //      border: 1px solid #000;
            //      width: @w + 4px;
            //      > .child {...}
            //    }
            //
            // And here's what the parse tree might look like:
            //
            //     Ruleset (Selector '.class', [
            //         Declaration ("color",  Value ([Expression [Color #fff]]))
            //         Declaration ("border", Value ([Expression [Dimension 1px][Keyword "solid"][Color #000]]))
            //         Declaration ("width",  Value ([Expression [Operation " + " [Variable "@w"][Dimension 4px]]]))
            //         Ruleset (Selector [Element '>', '.child'], [...])
            //     ])
            //
            //  In general, most rules will try to parse a token with the `$re()` function, and if the return
            //  value is truly, will return a new node, of the relevant type. Sometimes, we need to check
            //  first, before parsing, that's when we use `peek()`.
