PhpStorm 8.0.3 Node.js Connect use() undefined function or method

problem is caused by the way use(0 is defined in connect module:

module.exports = createServer;

var proto = {};
function createServer() {
  function app(req, res, next){ app.handle(req, res, next); }
  merge(app, proto);
  merge(app, EventEmitter.prototype);
  app.route = '/';
  app.stack = [];
  return app;
}

proto.use = function use(route, fn) {...}

Such dynamically added properties can hardly be resolved during static analysis

Great answer. Thanks!
