#1785: assign::list_of works poorly with class constructors
---------------------------+------------------------------------------------
 Reporter:  tailsu_at_[hidden]  |       Owner:  nesotto
     Type:  Bugs           |      Status:  new    
Milestone:  Boost 1.36.0   |   Component:  assign 
  Version:  Boost 1.35.0   |    Severity:  Problem
 Keywords:  list_of        |  
---------------------------+------------------------------------------------
 try compiling the following snippet:

  #include <boost/assign/list_of.hpp>
  using namespace boost::assign;

  class foo
  {
  public:
         foo(const vector<int>& a) {}
  };

  void bar()
  {
          foo a(list_of(0));
  }

 at the line 'foo a(list_of(0))' the compiler (VC8) thinks I want to call
 the copy contructor of foo, instead of the constructor that would cause a
 conversion to vector<int>. This case requires an explicit conversion, or
 using a different constructor prototype that doesn't overload the copy
 constructor.

 Please, advise which is the best way to use list_of in this scenario.
