[boost] [fusion] How does is_pointer< Sequence > work?

Hi Joel & Dan

Going through the fusion quick start, I'm wondering how the expression 
...

    for_each(filter_if<boost::is_pointer<Sequence> >(seq), print_xml());

... could ever work? Shouldn't that rather read similar to ...

    for_each(filter_if<boost::is_pointer<_> >(seq), print_xml());

... so that the _ placeholder can be replaced with the individual types 
in the sequence?

Thanks,
