    Description

      Currently ACID UpdateDeleteSemanticAnalyzer directly manipulates the AST tree but it's different from the general approach of modifying the token stream and thus will cause AST tree mismatch if there is any rewrite happening after UpdateDeleteSemanticAnalyzer.

      The long term solution will be to rewrite the AST handling logic in UpdateDeleteSemanticAnalyzer, to make it consistent with the general approach.

      This ticket will for now detect the error prone cases and fail early.
