VS2010和VS2012和C++ 11错误C2059：语法错误：'...'如何避开？

Question

我尝试编译simple C++11 code（我primaraly目标VS2010，也可以作为第二选择VS 2012）they say它应当编制，is compilable on some modern compilers 所以我不知道如何编译包含的代码结构，如：

struct C { 
    A *_first__; 
    B *_second__; 
    C(A * _first__, B * _second__):_first__(_first__), _second__(_second__) { 
    } template < typename K, typename ... T > static auto _a_caller__(K * k, T && ... args)->decltype(k->a(std::forward <T> (args) ...)) { 
    return k->a(std::forward <T> (args)...); 
    } 
    template <typename...T> auto a(T &&...args)->decltype(_a_caller__(_first__, std::forward <T> (args)...)) { 
     return _a_caller__(_first__, std::forward <T> (args)...); 
    } 
    template <typename...T> auto a(T &&...args)->decltype(_a_caller__(_second__, std::forward <T> (args)...)) { 
     return _a_caller__(_second__, std::forward <T> (args)...); 
    } 
    template < typename K, typename...T > static auto _b_caller__(K * k, T && ... args)->decltype(k->b(std::forward <T> (args) ...)) { 
     return k->b(std::forward <T> (args)...); 
    } 
    template <typename...T> auto b(T &&...args)->decltype(_b_caller__(_first__, std::forward <T> (args)...)) { 
     return _b_caller__(_first__, std::forward <T> (args)...); 
    } 
    template <typename...T> auto b(T &&...args)->decltype(_b_caller__(_second__, std::forward <T> (args)...)) { 
     return _b_caller__(_second__, std::forward <T> (args)...); 
    } 
}; 

在VS 2010和如果在vs2012中不可能呢？

可变参数模板不无论是在VS2010也不在VS2012支持：http://msdn.microsoft.com/en-us/library/vstudio/hh567368.aspx 他们在VS2012 CTP虽然支持：http://blogs.msdn.com/b/vcblog/archive/2012/11/02/visual-c-c-11-and-the-future-of-c.aspx

另见Variadic Template in VS 2012 (Visual C++ November 2012 CTP)如果你打算使用CTP。
