5968	phoenix bind and signals2 signal connect fails to compile	Lars Viklund <zao@…>	Thomas Heller	"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)
