CoffeeScript Bug: binding class methods with reserved names

gistfile1.coffee

class Test 
  export: =>


The js compilation I get is this (note the ' this."export" ')

var Test;
var __bind = function(fn, me){ return function(){ return fn.apply(me, arguments); }; };
Test = (function() {
  function Test() {
    this."export" = __bind(this."export", this);
  }
  Test.prototype["export"] = function() {};
  return Test;
})();
