Answer 1

The best way to do it is to use template_from_string twig function.

{{ include(template_from_string("Hello {{ name }}")) }}
{{ include(template_from_string(page.template)) }}

See documentation of template_from_string

See why it is not a good idea to use Twig_Loader_Chain or Twig_Loader_String for that purpose on this github issue by stof.
