[Templates] assigning to scalar passed as scalar reference

[Rodney Broom]

Yes, thank you both. I thought that Template::Stash copying prevented this, but hadn't tried.

My first use for this will be to put my canned-email subjects into the templates where they belong rather than in the code.

  $vars{stuff} = {};
  $tt->process($tmpl, \%vars, \$content);
  send_email(body => $content, subject => $vars{stuff}->{subject})
