template, implicit specialization?

Hi everyone, I've got this pice of code:

template <bool cond, typename A, typename B>
struct Select{
typedef A Result;
};

template <typename A, typename B>
struct Select<false, A, B>{
typedef B Result;
};

Select<false, char, float>::Result temp;

What is the second template supposed to be? An implicit specialization? It's
not an explicit one for sure.
If anyone could explain me what happens ...it would be great. thanx

A partial specialization.

What happens is that Select<false,char,float>::Result is float. For
such trivial example it is equivalent of:

float temp;

The usefulness of such contruct becomes more apparent in more complex
programs.
