# ============================================================
# Generator - 生成器（P1 骨架 + P2 多继承 Mixin 组合）
#
# 对象化重构宿主（wiki/14-oo-refactor.md）：
#   @t.NoVTable + 多继承（BaseGen 状态 + TypeGen 类型映射），方法沿
#   MRO 直接调用（Viper 多继承已支持，M1-M4）。后续 P3-P6 追加
#   StructGen/ExprGen/CallGen/FuncGen/ClassGen/StmtGen/ImportsGen Mixin。
#
# 注意：Viper NoVTable 继承只合并字段、不转发父类方法符号（子类调
# 父类方法 mangle 成子类名 → undefined reference），因此字段初始化
# 全部内联，不调用父类 Init* 方法。
