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})
