Why not to leave type name as it is, nil_t? It is less to type :) and it seems
there is no name conflicts. Then everyone could define theirs own literals as
they wish:

namespace {
        const boost::nil_t null;
        const boost::nil_t NoOneWantsToUseThisVeryLongName;
        const boost::nil_t nn; // for lazy people :))
}

and use temporary objects:

int f(boost::nil_t);
f(boost::nil_t());
