This will likely be _very_ relevant to the proposed changes which make ref and 
const ref work with rvalues (the details on that are still being sorted out, I 
believe). However, I don't believe that either Walter or Andrei pays attention 
to D.Learn, so if you want to bring it up for discussion, post about it in the 
main newsgroup (not to mention, your post is buried enough in this thread that 
many who _do_ pay attention to D.Learn wouldn't see it).
