Hi All,

1) I don't understand this part of reference_wrapper:

template<class T> class reference_wrapper
{
        operator T& () const { return *t_; }
};

Could someone please explain it?

2) Is there already a reference wrapper for n-ary functors which exposes 
the same result_type (if it exists) as the n-ary functor, but whose 
arguments types are arbitrary (deduced from the arguments)?
