[boost] Re: call_traits<int&>::value_type

It's not a compiler thing.  Look at the implementation:

http://www.boost.org/boost/detail/call_traits.hpp

template <typename T>
struct call_traits<T&>
{
   typedef T& value_type; // <-- problem here
   typedef T& reference;
   typedef const T& const_reference;
   typedef T& param_type;  // hh removed const
};

Thanks,
Eric
