[mpl]RFE: unpack_apply
Would it be possible to add: template<typename Application> struct unpack_apply { ... }; such that: is_same < unpack_apply<f<a0,a2,...,an> >::type , vector<a0,a2,...,an> > to mpl? Maybe a better name would be get_args, but since it's so closely related to unpack_args, I thought maybe unpack_apply could be considered OK.

Actually, I think I misunderstood unpack_args. The code in http://boost-sandbox.sourceforge.net/vault/ in: cppljevans/mpl/application_parts_test.cpp contains boost::mpl::application_parts2 which is what I want. It just applies to 2 arguments, but I guess it could be extended for 0..MAXARG arguments using boost/preprocessor. This could would be useful in classes like get_side_type (in same vault location) or any meta program which needs to dissect the parts of a template application.
