yuyan

豫言源码引号标识符迁移规则。用于编辑 .豫/.yuyan 编译器或库代码，把所有普通名字写成「」形式，同时保持语法关键字、列表括号、占位符、字符串字面量、注释和操作符声明结构正确。

Project-specific Yuyan migration rules for replacing local structure blocks such as `虑（...）` / structure-recursive declarations with expression-level `递归虑...其...者...而...` and `虑...者...而...`. Use when editing yylib or compiler `.豫`/`.yuyan` code to exercise the structure recursion operator / reclet syntax, especially when converting old structure declarations, local recursive helper functions, or direct expressions separated by `。`.

Manually remove yylib custom operator declarations and their supporting definitions from the Yuyan codebase, without Python or automated rewrites.
