... You cannot expand a template parameter pack to instantiate a non-variadic template.
Typically, this
template<typename... T> struct make_vector { typedef boost::mpl::vector<T...> type; }:
doesn't work.
GCC gives the error: sorry, unimplemented: cannot expand 'T ...' into a fixed-length argument list
And I believe the standard doesn't require it just because it would be difficult to implement in GCC's codebase.
My understanding is that the spec requires this to be well-formed code. Clang doesn't currently accept it, and I made a PR against it some time ago: http://llvm.org/bugs/show_bug.cgi?id=9021
