 * Hi,
 * Is it possible to make the plugin compatible with HHVM and Hack? WordPress is
   HHVM compatible with version 3.9 and Hack in the future 4.0. I am using and deploying
   WordPress installations in HHVM environment and would like to see this plugin
   workable, especially since there are other plugins that have dependencies on 
   your plugin.
 * I have run [Hackificator tool](http://docs.hhvm.com/manual/en/install.hack.conversion.php)
   and this is error log trying to switch your plugin files to Hack:
 *     ```
       ERROR HACKIFYING, UNDO: /home/robertsky/hack/projects/really-simple-captcha/really-simple-captcha.php (err = /home/robertsky/hack/projects/really-simple-captcha/really-simple-captcha.php:28:1,6: Remove all toplevel statements except for requires
