If the vars are allocated consecutively (in address space) then you must  
now wait for language extension to happen: ugly, but it works

| a b |
  a := b := 1.
  (1 to: 2) with: {a + 3. b + 4}
   do: [:ix :val | thisContext tempAt: ix put: val].
  ^ {a. b}

Same for iVars, example #forceNewFrom: :| and other clients of  
#instVarAt:put: ...
