Replying to e_r:

May I please suggest that a metafunction be provided that maps an mpl sequence such as

typedef mpl::vector<r1,...,rn> IN;

each r is of the form required<T> or required<T,P>

to the template class boost::parameter::parameters instantiated with the elements of that sequence:

typedef parameter::parameters<

r1, ... rn

OUT;

This need arises when we can generate IN automatically, for example:

typedef mpl::transform<range_c<1,n+1>,meta_r>::type IN;

Thanks.

Still on this problem. I'm wondering if mpl::unpack_args could to solve it.
