[boost] mpl::set problem

I can't understand why derefencing begin of set<int,char> gives
set2<int,char>, not char or int as one would expect.

    typedef set<int,char> s;
    typedef deref<begin<s>::type>::type e;
    BOOST_MPL_ASSERT(( or_<is_same<e,int>, is_same<e,char> > ));

If I change s definition to

    typedef insert<set<int>,char>::type s;
    
it compiles fine on gcc 3.4 and intel-linux 8.0.
