[boost] [ref] provide unref( T& )?

Hi,

To be able to call a function object wrapped in 
boost::reference_wrapper<T>, we need something like the following:

template< class T >
inline typename boost::unwrap_reference<T>::type&
unref( T& value )
{
     return static_cast<typename 
boost::unwrap_reference<Fun>::type&>(value);
}

which can then be used like

template< class Fun >
int algorithm( Fun fun )
{
     return unref(fun)(42);
}

any objections to adding this to ref.hpp?
