here’s a subtle but important consequence: in RE#, rewriting your regex using boolean algebra is always safe. factor out common prefixes, distribute over union, apply de Morgan’s laws - the matches won’t change. your regex is a specification of a set of strings, and the engine faithfully finds the leftmost-longest element of that set in the input. no surprises from alternation order, no “well it depends on how PCRE explores this search tree”. just set theory.
