 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,
 MAT.
