Sorry, I was confused. I think I wanted to simplify

fun(
  (
   kwd<1>::value = arg1, // parameter::keyword<tag<1> >& kwd<1>::value
   ...
   kwd<n>::value = argn  // parameter::keyword<tag<n> >& kwd<n>::value

  )
)

and I should have probably looked for something like this

typedef parameter::parameters<
  required<tag<1> >,
  ...,
  required<tag<n> >
 > spec;

fun(
  spec(arg1,...,argn)
)

So now, how to I create spec automatically?

template<std::size_t First,std::size_t Last>
struct spec{ //First = 1, Last = n+1 in the example above

  typedef ... type;

};
