perex 0.1.12 (PerryTS/perex#4): alternatives that cannot begin at the current character are skipped without a backtracking frame, so large alternations like an emoji-width regex stop backtracking through every branch. In perry, `emoji.test(c)` 3,396 -> 2,123 instructions per call, `ns.default().test(c)` 3,865 -> 2,593, Claude Code string-width per grapheme 15,161 -> 13,825; commander -0.32%, fastify -0.18%, qs parse -0.18% instructions.
