   Hi.  I just started reading a copy of a C++ draft I got several months   
   ago (n3282.pdf, I think).  I have some quick questions.   
      
   1. Let's say my class can take several arguments of the same type.  I   
   also want to take zero arguments, as a default constructor, and one   
   argument as a conversion.   
      
   template < typename T >   
   class my_complex   
   {   
   public:   
       my_complex() = default;   
       my_complex( T first );   
       my_complex( std::initializer_list list );   
   //...   
   };   
      
   If I just use the initializer constructor, and get rid of the other   
   two, would I still need the braces when I use zero or one argument?   
   Or do I need all three constructors if I need brace-less construction   
   with zero or one arguments?   
      
   2.  Maybe I missed something, or I haven't read the applicable section   
   yet, but what's with the   
      
   class my_class   
   {   
   public:   
       void  f() &;   
       void  f() &&;   
   };   
      
   construct?  What's it do?  What's it for?  How does it differ from   
   returning a reference?
