I have been going over the changes and I recall some more stuff now. Before I disabled creating references to rvalues, `boost::ref` was doing "accidental reference collapsing" for two levels of wrapping.

I'm not sure I understand. Can you post the code example that demonstrates the accidental collapsing before the rvalue change?
