Good point!

OK. But why add so much talk about the component types here?

     The following expression produces a function type for variadic function.
     Since a calling convention isn't specified, the default calling convention
     is used.

       function_type<mpl::vector<void,int>, variadic>::type // is void (int...)

Should be enough, right?
