I don't think this is too much code to expect people to write:

  $row{__selected__} = "selected" if $value;

That's really all you're talking about, right?

Because CGI.pm already has it nailed.  Why reinvent the wheel?  And
you can't beat the simplicity:

  $template->param(year_select =>
                   scalar $query->popup_menu(-name => 'year',
                                             -values => [ 1970 .. 2020 ])
                  );

And in the template:

  <tmpl_var year_select>

I've been doing it for years now and it's never done me wrong.
