I wouldn't say they are completely different and unrelated. They 
both result in rvalues being attached to a reference. The only 
difference is one only allows rvalues specifically. It'd be a bad 
idea to allow both implementations, imo. It'd just complicate 
things further. Kind of a shame this was approved as a project, 
couldn't something else have been approved that didn't have a 
chance for the work to just be thrown away...
