I just switched from 39 to 40 and my proto code that was working doesn't 
anymore.
I define a grammar that matches any terminal, any nary functions except 
for address_of and comma like this :

struct grammar
: bp::or_< bp::terminal< block<bp::_,bp::_> >
, meta::lambda_term< boost::is_arithmetic >
, bp::and_< bp::nary_expr< bp::_, bp::vararg< grammar > >
, bp::not_< meta::low_level<bp::_> >
, bp::not_< meta::stream<bp::_,bp::_> >
 >
 > {};

where lambda_term is :

template< template<class> class Lambda >
struct lambda_term
: boost::proto::and_< boost::proto::terminal<boost::proto::_>
, boost::proto::if_<Lambda<boost::proto::_value>()>
 > {};

When i compile any code that instanciate my grammar, i got :

/usr/local/include/boost-1_40/boost/proto/matches.hpp:304: error: 
invalid use of incomplete type ‘struct 
boost::proto::op::address_of<boost::proto::wildcardns_::_>’

While I got no error in 1.39
Do I miss some include of core proto file that wasn't needed before ?
