This can be done using boost::type_traits::add_**reference I believe:

Actually there is a declval somewhere in boost that more or less does this, unfortunately it returns by value in C++03, which is a big no-no for me, since it restricts it to copyable types.
[At the risk of drifting off-topic...] If you're worried about that, shouldn't you be using declval<T&>() if you really want an lvalue? - Jeff
