deduce element type of c-array template argument

[Maik]

Hi,

What is ?? in
<code>
template< typename T >
struct element_type
{
typedef ?? type;
};
<code>
so that i.e
boost::is_same<element_type<float[3]>::type, float>::value
is true?

Thanks in advance,

template <typename T>
struct element_type;

template <typename T, size_t N>
struct element_type <T [N]>
{
typedef T type;
};
