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.
