and this is the crux of why we care: extended operators do not make sense with an ordered OR. if | isn’t commutative, then boolean algebra falls apart. A & B is supposed to equal B & A. ~~A is supposed to equal A. these identities rely on | being true union, not “try left first”. so if you want & and ~ to work correctly, you need commutative semantics. it’s not a style choice, it’s a mathematical necessity. and surprisingly also a reason for our amazing benchmark results - leftmost-longest lets you simplify your regexes without changing the matches, which i will elaborate on in another post, but for now just take my word for it that this is a huge deal for performance.

以高品质生活标定高质量发展新方向。新时代的高品质生活，核心是从“有没有”向“好不好”全面升级，目的是让高质量发展始终围绕人民的高品质生活需求调整方向、配置资源、优化路径。具体可从4个维度推进。一是以民生需求指引产业发展方向，如围绕健康需求，推动生物医药、智慧医疗等产业发展；对接宜居需求，推动绿色建筑、智能家居等产业发展。二是以公共服务均等化校准资源配置方向，如聚焦农业农村现代化，逐步提高农村基础设施完备度、公共服务便利度、人居环境舒适度。三是以共同富裕目标引领分配改革方向，如拓宽居民财产性收入渠道，扩大中等收入群体规模。四是以绿色低碳转型明确发展模式方向，如严控高耗能、高排放项目，推进生态产品价值实现，让人民群众在绿水青山中享受高品质生活。
