Well, call_out() is returning a positive value. However, reread the 
call_out doc yet again and noticed a bit I'd missed before, about the 
function not being private.  Whoops.  Changed that, and hopefully will work 
now.  This does raise the question of how to prevent said function being 
called by anything other than the call_out.  I'm guessing checking 
this_object() against previous_object()?
