巷子里有自己一年一度的“春晚”。大人们搬起小凳子坐在树下，我们几个孩子自告奋勇，上台表演——节目全是模仿大人看的那些。每个人都身兼数职，忙得不亦乐乎：走完模特步，要接着唱流行歌，还要讲段小品。这是真正意义上的“草台班子”：唱跑调了就鼓掌，跳错了就重来，忘词了就现编。
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!
