#2674: request to make BOOST_PARAMETER_MAX_ARITY re-defineable

     Type:  Feature Requests  |      Status:  new      
Milestone:  Boost 1.38.0      |   Component:  parameter
  Version:  Boost 1.37.0      |    Severity:  Problem  
 Keywords:                    |  
------------------------------+---------------------------------------------
 I'd like to be able to increase BOOST_PARAMETER_MAX_ARITY in my library
 header if needed, and then include the Boost.Parameter library without
 worrying that the user might have already included Boost.Parameter headers
 and thus made my attempt to increase the max arity futile.  I believe the
 Boost.Function library has this feature.  My use case is trying to apply
 Boost.Parameter to the boost::signals2::signal class, which currently has
 7 template type parameters (but BOOST_PARAMETER_MAX_ARITY defaults to 5).
