gistfile1.js

  var œ = function(number) {
    return {
      times: {
        length: number,
        "do": function(fn) {
          var len = this.length;
          for (var i = 0; i < len; i++) {
            fn(i);
          }
        }
      }
    };
  };

  œ(20).times.do(function(i) { console.log(i); });
