This way, we get:
copy<c_list>(std::back_inserter(r_list));
Output of a compile-time sequence is also trivial:
copy<c_list>(std::ostream_iterator<int>(std::cout,","));
Thinking about this some more, the only reason this works is that the sequence consists of elements of the same type (integral_c derived), and that it has an implicit conversion to the value type.
However, it would also be possible to support heterogenous sequences, but then, the standard iterator adapters aren't sufficient, as they only work for homogenous sequences. That's possible to make, though.
For fun, I knocked up this program, which stores values of a variety of types in a compile-time sequence (char, int, double, rational_c and std::string (wrapped)), prints the sequence out, copies it to a run-time sequence (using boost::variant as element type), and prints it out, again.
You seem to be treading heavily into the territory of boost::fusion here, no? -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
