Comment (by viboes):

 In addition to your variadic patch I'm ready to provide the up to 9
 version for

 {{{
         template<typename T,typename A1,typename A2,typename A3,typename
 A4>
         inline T* heap_new_impl(A1 a1,A2 a2,A3 a3,A4 a4)
         {
             return new T(a1,a2,a3,a4);
         }

 }}}

 but not for the mix of const/non-const ref variant

 {{{
         template<typename T,typename A1,typename A2>
         inline T* heap_new(A1 const& a1,A2 const& a2)
         {
             return heap_new_impl<T,A1 const&,A2 const&>(a1,a2);
         }
         template<typename T,typename A1,typename A2>
         inline T* heap_new(A1& a1,A2 const& a2)
         {
             return heap_new_impl<T,A1&,A2 const&>(a1,a2);
         }
         template<typename T,typename A1,typename A2>
         inline T* heap_new(A1 const& a1,A2& a2)
         {
             return heap_new_impl<T,A1 const&,A2&>(a1,a2);
         }
         template<typename T,typename A1,typename A2>
         inline T* heap_new(A1& a1,A2& a2)
         {
             return heap_new_impl<T,A1&,A2&>(a1,a2);
         }
 }}}

 Of course, a patch using preprocessor programming is welcome.
