From 5fcf7821ad711a4968b9fba47fe018186875a495 Mon Sep 17 00:00:00 2001 From: "Flavio S. Glock" Date: Tue, 28 Apr 2026 21:39:25 +0200 Subject: [PATCH] docs: document bundled Moose 2.4000 stack MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reflect that PerlOnJava now ships Moose and Class::MOP 2.4000 in the JAR — `use Moose;` works out of the box. DBIx::Class is not bundled; it (along with Moo, its dependency) is installed via `jcpan` from CPAN. Updates: - README.md: feature bullet now includes "Moose / Class::MOP". - docs/reference/bundled-modules.md: - New "Moose / Class::MOP" section with usage example, status table, known limitations, and performance notes. - OOP & Introspection table grew Class::MOP, Moose, B entries. - DBIx::Class explicitly noted as installed via jcpan, not bundled, and depending on Moo (also from CPAN). - docs/reference/feature-matrix.md: Objects section gains a Moose / Class::MOP bullet. - docs/about/changelog.md (v5.42.3 unreleased): bundled-Moose entry. - docs/about/roadmap.md (Recently Completed): same.
