[boost] lexical_cast to self

In generic code lexical_cast<> is sometimes used as a cast to the same  
type. I would like to shortcut this rather then going all the way by  
writing it to a stream and reading back. In my code I use the following  
workaround:

template<class U, class T>
inline typename boost::disable_if<boost::is_same<T, U>, U>::type  
lexical_cast(T const& t)
{
     return boost::lexical_cast<U>(t);
}

template<class T>
inline T const& lexical_cast(T const& t)
{
     return t;
}

Does it make any sense to put it in lexical_cast.hpp?
