Return value missed within the closure after browserified

问题

My original script looks like this:

(function() {
    // result = doSomeWorks()
    return result;
})();

Which I can get a return value from APIs like chrome.tabs.executeScript or execute_script of selenium/webdriver.

But after the script being browserified (http://pastebin.com/7dBJuGzL), the return value seems just missed. I always get a null value from the above APIs.

Is there any solution/workaround for this? Or maybe trying to get the return value from a browserified script it just not idiomatic to Browserify?

Thanks in advance.
