of course this rabbit hole goes deeper, and we have a paper using this technique for string constraint solving that i’d love to derail this post into, but i’ll save that for another time. the main point is that symbolic derivatives are a more powerful and efficient generalization of Brzozowski’s original idea, and they form the core of the new RE# engine. fun fact: symbolic derivatives are also implemented in Z3 (the SMT solver) for its sequence theory - so in some sense we’re inching closer to having an SMT solver’s core machinery inside a regex engine.

但需提醒：该特性虽优秀（笔者公司已在生产环境使用），但目前采用难度高于多数C++功能，主要因缺乏完善文档及基础辅助库。现阶段建议在已有经验者指导下学习，并编写适配库以整合现有异步代码与std::execution。
