c++0x and rvalue references on gcc 4.6.1

[leon zadorin <leonleon77@xxxxxxxxx>]

Hi everyone.

Just started looking-into/reading-on c++0x rvalue refs and would like
clarification on the following code being compiled by gcc v 4.6.1 (on
freebsd 8.2 release, amd64):

#include <iostream>
struct init {};
struct x {
  template <typename InitPolicy>
  void
  init_from(InitPolicy const & x)
  {
    ::std::cout << "by ref\n";
  }
  template <typename InitPolicy>
  void
  init_from(InitPolicy && x)
  {
    ::std::cout << "by rvalue ref possibly stealing resources held by x\n";
  }
};

int
main()
{
  x x1;
  init i;
  x1.init_from(i);
  return 0;
}

compiled with:
c++ -std=c++0x main.cc
produces:
"by rvalue ref possibly stealing resources held by x"

>From various experiments, the above 'x1.init_from(i)' binds as
'x1.init_from<init&>(i)' [as opposed to 'x1.init_from<init>(i)]... but
even if so -- I was wondering how does this correlate with the
following quote from wiki on c++11:
http://en.wikipedia.org/wiki/C%2B%2B0x#Rvalue_references_and_move_constructors
"... A named variable will never be considered to be an rvalue even if
it's declared as such; in order to get an rvalue, the function
template std::move<T>() should be used ..."

I am most likely missing something simple here (just starting to read
no rval refs...)

Best regards
