uses a recursive call using a List which is 1 shorter
than the argument list, List.
Why not just pass sizeof...(T0, Ts...):
http://en.cppreference.com/w/cpp/language/sizeof...
and keep adding indices while decreasing this sizeof value,
as done here:
http://svn.boost.org/svn/boost/sandbox/variadic_templates/boost/mpl/package_...
in the package_range_c template class where:
Start value would be 0
and Finish value would be sizeof...(T0, Ts...)
It achieves the same result, but without producing unneeded
instantiations. For example:
package_range_c>::type
package_range_c>::type
would produce 1 instantiation of:
package_range_cstd::size_t,0,3
whereas the int_list.hpp code would, IIUC, produce the same
instantiations for the T's as well as the S's.
