Okay, from this moment MPL's lambda supports "reduced" metafunction form
directly (if detected):

    template< typename T > struct her
    {
        // no 'type' member!
    };

    typedef lambda< her<_> >::type f;
    typedef apply<f,int>::type t;

    BOOST_MPL_ASSERT_IS_SAME(t, her<int>);

The "ordinary" metafunctions work as before.

Enjoy!
