Catalyst::View::TT has a render

Catalyst::View::TT 从 0.23 起将多了一个函数叫做 render. 一个最常见的用法是：

   $c->email(
      header => [
        To      => 'me@localhost',
        Subject => 'A TT Email',
      ],
      body => $c->view('TT')->render($c, 'email.tt', {
        additional_template_paths => [ $c->config->{root} . '/email_templates'],
        email_tmpl_param1 => 'foo'
        }
      ),
    );

以前我们经常得用 SubRequest 来做这事。
可看起来 render 似乎更干净一些。:)
