July 2026 — Perl/perl5: Major modularization of APItest XS bindings and a broad RegExp engine overhaul, delivering clearer module boundaries, improved test reliability, and stronger cross‑platform stability. Key deliverables include splitting APItest.xs XSUBs into dedicated modules (utf8, hash, ptr_table, TempLv, AutoLoader, Magic, backrefs, HvMacro, BoolInternals, RWMacro, CvREFCOUNTED_ANYSV, global_locale, savestack, vstring, Unicode charclass) and splitting Unicode XSUBs; modularizing the remaining APItest.xs XSUBs with test rebalancing and documenting split points. RegExp work includes trie/regops refactors, bespoke trie node accessors, removal of opcode‑order dependencies, long‑trie support, and a data‑driven regcomp.sym plus a low‑diff regnodes format; added safety assertion and Windows compiler warning handling. Infra/quality gains include updating .gitignore to ignore .ccache, reducing test noise in trie overflow tests, a makedepend infra fix, and memEQ/memEQs usage notes. Business impact: sharper maintainability, faster feature delivery, more reliable CI tests, and a stronger foundation for regex and XS bindings.
