<pre>Consider the following example :
----------------------------------------
#include <iostream>
#include <tuple>
template <class Type>
struct Getter
{
template <unsigned int Index = 0, class Tuple>
static inline Type get(const Tuple& tuple);
};
template <class Type>
template <unsigned int Index, class Tuple>
inline Type Getter<Type>::get(const Tuple& tuple)
{
return std::get<Index>(tuple);
}
int main(int argc, char* argv[])
{
std::cout<<Getter<int>::get(std::make_tuple(42))<<std::endl;
return 0;
}
----------------------------------------
Under "clang++ 3.2-1~exp9ubuntu1", it produces the following error :
----------------------------------------
defaulttemplate.cpp:12:37: error: template parameter missing a default argument
template <unsigned int Index, class Tuple>
^
defaulttemplate.cpp:7:36: note: previous default template argument defined here
template <unsigned int Index = 0, class Tuple>
----------------------------------------
If the member is defined inside the class declaration, clang++ does not
complain anymore.</pre>
