Yep, it's not. It's a known failure, which I didn't have time to track down
yet... hmm, apparently, it's a Metrowerks bug:

    #include "boost/mpl/aux_/has_xxx.hpp"
    #include "boost/static_assert.hpp"

    BOOST_MPL_HAS_XXX_TRAIT_DEF(begin)

    struct UDT {};
    struct begin {};

    int main()
    {
        BOOST_STATIC_ASSERT(!has_begin<UDT>::value);
    }

I reported it to their tech-support.
