Re: [Boost-users] Boost.Variant: Passing visitor as a function argument

...

   void  visit(boost::static_visitor<> const& visitor)    {        BOOST_FOREACH(Attr attr, i_attrList)        {            boost::apply_visitor(visitor, attr);        }    }

Just for note, but considering that you are asking for a static_vistor directly, and you create a visitor by using the CRTP, this shows that you might want to learn a little bit more about how C++ handles classes before delving into too much more.
