there’s a ton of bugs in industrial applications that come from this kind of “it depends” behavior, and it’s a nightmare for testing and maintenance. even LLMs get this wrong all the time because they’ve been trained for an eternity of people getting it wrong all the time - you wouldn’t believe the types of human-hallucinated answers there are out there on stack overflow. perhaps one last thing to say here is that leftmost-longest can express every single pattern that leftmost-greedy can. it is a more general form. want to return the same results from (a|ab)+ as PCRE? just rewrite it as (a)+ - that’s what it is. the very fact that there is a difference at all means that there was a bug in the PCRE pattern, ab is an unreachable branch.

跟杜太白一样，刘震云也当过民办教师，时间不长，教龄只有两个月。令人意外的是，他教的并不是语文，而是高中数学。从念初中开始，他便迷上了数学，觉得那是乐趣无穷的学科，代表一个完整、玄妙而又变幻无穷的系统。“我的数学全靠自学。不懂数学或者不愿意学数学的人，可能会觉得那是特别枯燥的门类，但其实你真正钻进去，你就能理解数学家，甚至理解自然科学那种独特的理性，有时这种理性甚至来自感性。”
