Milestone:  To Be Determined           |   Component:  phoenix
  Version:  Boost 1.47.0               |    Severity:  Problem

---------------------------------------+------------------------------------
 Using a Phoenix bind in a Signals2 signal fails to compile with errors in
 either fusion::category_of where actor is missing the category type (in
 1.47.0), or in phoenix visit_each (in trunk r74198).

 {{{#!c++
 #include <boost/phoenix.hpp>
 #include <boost/signals2.hpp>

 struct s
 {
         bool f(int, bool) { return true; }
 };

 int main()
 {
         s s_obj;
         boost::signals2::signal<bool (int, bool)> sig;
         sig.connect(
                 boost::phoenix::bind(
                         &s::f, &s_obj,
                         boost::phoenix::placeholders::arg1,
                         boost::phoenix::placeholders::arg2));
 }
 }}}

 Simplifying the bind to the following expression has the same results:
 {{{#!c++
 (val(&s_obj)->*&s::f)(arg1, arg2)
 }}}
