I met some difficulties improving this pass. For now, I'm not going to take over it. This pass massively utilizes low level semantics such as `PostOrderVisit` (instead of `StmtExprMutator`) and raw pointers to `Object`, and it relies on manually tracking the updates to these pointers, which is hard to understand. Maybe we should develop an improved `StmtExprMutator`, which can track the updates to the nodes. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
