<<C++ Template>>书的源代码编译不过,为什么?
这本书的随书源代码，我在VC10下面试验了一下，发现竟然编译不过:

C/C++ code

#include<deque>
template <typename T,
          template <typename ELEM> class CONT = std::deque >//编译器报错！！！！！！！
class Stack {
  private:
    CONT<T> elems;         // elements

  public:
    void push(T const&);   // push element
    void pop();            // pop element
    T top() const;         // return top element
    bool empty() const {   // return whether the stack is empty
        return elems.empty();
    }
};
template <typename T, template <typename> class CONT>
void Stack<T,CONT>::push (T const& elem)
{
    elems.push_back(elem);    // append copy of passed elem
}

template<typename T, template <typename> class CONT>
void Stack<T,CONT>::pop ()
{
    if (elems.empty()) {
        throw std::out_of_range("Stack<>::pop(): empty stack");
    }
    elems.pop_back();         // remove last element
}

template <typename T, template <typename> class CONT>
T Stack<T,CONT>::top () const
{
    if (elems.empty()) {
        throw std::out_of_range("Stack<>::top(): empty stack");
    }
    return elems.back();      // return copy of last element
}

int _tmain(int argc, _TCHAR* argv[])
{
    return 0;
}

VC提示说: error C3201: the template parameter list for class template 'std::deque' does not match the template parameter list for template parameter 'CONT'

我想问，这里的模板写法:
template <typename ELEM> class CONT = std::deque
是否符合C++规范? 为什么要用到嵌套的template声明，<typename ELEM>根本就没有用到啊


------解决方案--------------------
读书还得再认真一点，下面是摘抄 c++-templates 的原话，就在主楼例子程序下面不远。

If you try to use the new version of Stack , you get an error message saying that the default value std::deque is not compatible with the template template parameter CONT. The problem is that a template template argument must be a template with parameters that exactly match the parameters of the template template parameter it substitutes. Default template arguments of template template arguments are not considered, so that a match cannot be achieved by leaving out arguments that have default values.

The problem in this example is that the std::deque template of the standard library has more than one parameter: The second parameter (which describes a so-called allocator) has a default value, but this is not considered when matching std::deque to the CONT parameter.

再往下该书给出了一个能编译的程序。
