For perfect forwarding use:

template<class... T>
void call(T&&... t)
{
   foo(std::forward<T>(t)...);
}

I tried this one too and it works fine thank you.

However, I use these functions with boost::bind library and actually references
are lost when I use it (and I need to). After some google searches, it seems that 
boost::bind officially does not support this use (due to internal references).
So I tried with std::bind because I read somewhere the problem was fixed with its C++11 version.
The problem is the same : with std::bind too, references are lost using std::forward.

Does anyone made this duo bind/template variadic functions working together ?
And if someone did, how did you do ?
