Comment (by Peter Schüller <schueller.p@…>):

 sorry to say that, but [67366] broke something:

 define the following function inline solves the problem (line 105 in
 debug.hpp):
 {{{
         inline std::ostream &operator <<(ostream_wrapper sout_wrap,
 named_any t)
 }}}
 otherwise I get duplicate symbol definitions if I use spirit in two
 compilation units:
 {{{
 /...path.../proto/debug.hpp:105: multiple definition of
 `boost::proto::hidden_detail_::operator<<(boost::proto::hidden_detail_::ostream_wrapper,
 boost::proto::hidden_detail_::named_any)'
 }}}
