TalkPHP - Expected an assignment or function call and instead saw an expression?

Problem at line 12 character 12: Expected an assignment or function call and instead saw an expression.

this.todo;

Strange. Why does jslint.com errors out?

Code:

jQuery(document).ready(function() {

  /**

   * sliceDo iterates slice array, evalutes the toDo array as javascript under click event for each slice based on slice index.

   * @param array slice

   * @param array toDo

   */

  sliceDo = function(slice) {

    jQuery.each(slice, function(index, value) {

      jQuery(value).click(function(){

        return false;

      });

      this.todo;

    });

  };



  // Array of slices of Pie Menu

  slice = jQuery('#pie').children();



  // Work to be done by the slices

  var work = {

    todo: jQuery(slice[1]).mouseover(function(object) {

      menuOffset = jQuery('.pie_menu').offset();

      jQuery('#pie_right').show().css({top: menuOffset.top + 50 + 'px', left: menuOffset.left + 140 + 'px'});

    }).mouseout(function() {

      jQuery('#pie_right').hide();

    })

  };



  sliceDo.apply(work, [slice]);



  jQuery('.search-results > li').children().click(function(object){

    jQuery('.pie_menu').show().css({left: object.pageX + "px", top: object.pageY-10 + "px"});

    return false;

  });

});
