今天因为 OpenClaw 来的用户，明天可能因为别的 Agent 产品来；但只要用户习惯了在他们的平台上部署 Agent，这些用户就成了长期绑定的客户。云厂商们做的，是提前占位，建立用户习惯，构建生态壁垒——卖铲子的生意，往往比挖金子的人更稳定，也更赚钱。
One of the nice things about Ostrich is that it contains an extension to the SMT-LIB constraint standard to parse and handle ECMA regular expressions. Well, not all of them; ECMA and other PCRE-derived regexes are in fact not regular (2022 paper) and cannot in theory be represented accurately for string-solving purposes. In practice, though, that's rarely a problem. Ostrich also contains cool tricks to some of the traditionally difficult/impossible regex features, developed for Black Ostrich. You can read about them in the director's cut version of our paper!
