There are a few "evil" CGI.pm HTML shortcuts that generate multiple elements,
and so they show up as ARRAY(0x...) in your output.  I don't know a rule
for it, but almost all of the "group" input items do (the ones that
take a hashref or array ref to generate multiple things).

The solution is to tack a tacky .join("") on the end, as in:

   CGI.popup_menu( ... ).join("");

That's what I've been using.  If there's a simpler solution (Andy?)
I'm all for it.
