I wanted to find out about the status of the rvalue reference proposal.
Has it been implemented in any real-world compiler? Is it at least
somewhat likely to make it into a future C++ language standard?

The reason I'm asking is that 3 weeks ago I downloaded a GCC 4.0
tarball and started hacking in support for n1377. At this point, I've
got what I consider the core of the proposal (parsing && types, binding
them to rvalue expressions, and using them to resolve function
overloads) implemented, though I figure I'm only about a third of the
way towards my goal of having a polished, complete patch to submit for
inclusion with GCC. Since I've never really tracked the C++
standardization process or the development of GCC, I want to make sure
I'm not wasting or duplicating effort before I go further. Any
information or words of advice would be appreciated. My current patch
for GCC is available at http://russ.hn.org/rref/
