as_named is needed if you allow an argument slot to accept both
unnamed and named template parameters.
You should be able to go around the need for template template 
parameters by 'expanding' as_name by hand:

instead of 

typename boost::ntp::as_named<Model, Model_is>::type

write:

typename boost::mpl::if_c<detail::is_named_parameter<Model>::value,
                          T, Model_is<T> >::type

Are there other things that cause trouble with your compiler?
