Hey, question.module is great! Help me update for 4.7, please?

Hi,

I'd love to use this module on a 4.7 installation, if possible. I updated it for drupal's 4.7 forms api (by running the code through formupdater - hey, that's another neat module!) and I've attached the resulting module file.

Now I'm just left with this error to debug:

Fatal error: Cannot create references to/from string offsets nor overloaded objects in /home/xaccountx/public_html/drupaldir/includes/form.inc on line 312

I'm testing on drupal cvs 2/28. Line 312 of form.inc is:
    $form['#ref'] = &$ref;

Any chance someone could help with this? Are there plans to support this module for 4.7?
