6026	phoenix block statement tries to copy objects instead of references	armagvvg@…	Kohei Takahashi	"Let's use a simplest class, that can't be copied:

{{{
class A {
   A() {}
   A(const A&);
public:
   static A* construct() { return new A(); }
   const A& operator<<(const char *p) const { return *this; }
};

A *pa = A::construct();
A &a = *pa;

}}}

The code which use this object one time normally works:
{{{ 
(boost::phoenix::ref(a) << boost::phoenix::placeholders::_1)(""aaa"");
}}}

But when I try to use this object two times, I get an error:
{{{
(
   boost::phoenix::ref(a) << boost::phoenix::placeholders::_1
   ,boost::phoenix::ref(a) << boost::phoenix::placeholders::_1
)(""aaa"");
}}}

Result: 'A::A' : cannot access private member declared in class 'A'

Expecting: pass compilation and invoke ""A::operator<<"" two times.
