   > 2. why shouldn't eliminate project in the translator?
   
   i can answer the 2nd question.
   currently, we use two map to maintain ExprId and SlotId's relationship. However, in some cases, this cannot work fine when we eliminate project in translator. Instead, we need to maintain a 1 to n relationship. And in some other cases, we find more than one bugs in this feature's code.
   So, we just remove this feature temporarily and add it back later~
