7165	cannot change BOOST_PHOENIX_LIMIT	m.champlon@…	Thomas Heller	"Hi !

The following code :
 #define BOOST_PHOENIX_LIMIT 20
 #include <boost/phoenix.hpp>
fails to compile with boost 1.50 and msvc 2010 with an error trace starting with :
 1>C:\dev\include\boost/phoenix/core/preprocessed/actor_30.hpp(10): error C2977: 'boost::proto::and_' : too many template arguments
 1>          C:\dev\include\boost/proto/matches.hpp(784) : see declaration of 'boost::proto::and_'

The following compiles :
 #define BOOST_PHOENIX_LIMIT 20
 #define BOOST_PROTO_MAX_LOGICAL_ARITY 20
 #include <boost/phoenix.hpp>

In http://boost.2283326.n4.nabble.com/phoenix-not-playing-nice-with-other-libs-td3489758.html Eric Niebler seems to suggest that proto::and_ should be split and nested to avoid having to change BOOST_PROTO_MAX_LOGICAL_ARITY, wouldn't that solve the issue ?

Thanks,
