   That is the same as register allocation for an unbounded set of   
   registers. I'm not sure why you mean by "color-out", but you'd have to   
   track liveness and conflicts to accomplish the renaming at which point   
   you're very close to a full allocator.   
      
   My main point was that just dropping the subscripts doesn't work.

   Certainly.
