[boost] [mpl] is_lambda_expression bug?

The compile-time assertion fails in the following program. I have tried with
more than one version of boost including 1.53.

Is it a bug? Shall I report it?

--------------------------------------------------

#include <boost/mpl/assert.hpp>
#include <boost/mpl/lambda.hpp>
#include <boost/mpl/plus.hpp>

namespace mpl = boost::mpl;

struct MetafunctionClass
{
        template<typename T1, typename T2>
        struct apply
        {
                typedef	typename mpl::plus<T1,T2>::type type;
        };
};

BOOST_MPL_ASSERT((mpl::is_lambda_expression<MetafunctionClass>));

int main(int argc, char * argv[])
{
}
