Undefined pseudo-variables

Thanks, but that means I have to do that manually in each controller.

For example, if I'm using the same template for all pages, including pages with contact forms on, I want to have {feedback} for form feedback. Now instead of defining $data->feedback = false; in all controllers that use the same template, I'd like to extend the template / parser to set any undefined pseudo-variables as false.

I'm guessing this isn't easy though, as the template / parser would need to know what variables are waiting in the template file.
