模板，可变参数函数，通用引用和函数指针:爆炸性的鸡尾酒

请考虑以下代码和apply函数：

// Include
#include <iostream>
#include <array>
#include <type_traits>
#include <sstream>
#include <string>
#include <cmath>
#include <algorithm>
// Just a small class to illustrate my question
template <typename Type, unsigned int Size>
class Array
{
    // Class body (forget that, this is just for the example)
    public:
        template <class... Args> Array(const Args&... args) : _data({{args...}}) {;}
        inline Type& operator[](unsigned int i) {return _data[i];}
        inline const Type& operator[](unsigned int i) const {return _data[i];}
        inline std::string str() 
        { 
            std::ostringstream oss; 
            for (unsigned int i = 0; i < Size; ++i) 
                oss<<((*this)[i])<<" "; 
            return oss.str();
        }
    protected:
        std::array<Type, Size> _data;
    // Apply declaration
    public:
        template <typename Return, 
                  typename SameType, 
                  class... Args, 
                  class = typename std::enable_if<std::is_same<typename std::decay<SameType>::type, Type>::value>::type> 
        inline Array<Return, Size> apply(Return (*f)(SameType&&, Args&&...), const Array<Args, Size>&... args) const;
}; 
// Apply definition
template <typename Type, unsigned int Size>
template <typename Return, typename SameType, class... Args, class> 
inline Array<Return, Size> Array<Type, Size>::
apply(Return (*f)(SameType&&, Args&&...), const Array<Args, Size>&... args) const
{
    Array<Return, Size> result; 
    for (unsigned int i = 0; i < Size; ++i) {
        result[i] = f((*this)[i], args[i]...);
    }
    return result;
}
// Example
int main(int argc, char *argv[])
{
    Array<int, 3> x(1, 2, 3);
    std::cout<<x.str()<<std::endl;
    std::cout<<x.apply(std::sin).str()<<std::endl;
    return 0;
}

编译失败，并显示：

universalref.cpp: In function ‘int main(int, char**)’:
universalref.cpp:45:32: erreur: no matching function for call to ‘Array<int, 3u>::apply(<unresolved overloaded function type>)’
universalref.cpp:45:32: note: candidate is:
universalref.cpp:24:200: note: template<class Return, class SameType, class ...

universalref.cpp:45:32: note:   mismatched types ‘SameType&&’ and ‘double’
universalref.cpp:45:32: note:   couldn't deduce template parameter ‘Return’

我不太确定为什么它会失败。在该代码中，我想要：

• 保持通用引用具有最通用的函数
• 能够使用语法apply(std::sin)

那么我必须更改什么才能使其编译？
