Dec 1, 2025Month 2025-12 summary for rakudo/rakudo: - Delivered a critical bug fix addressing the Raku Anonymous Role Scope issue. The default scope for unnamed packages was changed from 'our' to 'anon' to correctly support declaring roles within roles, eliminating a long-standing ambiguity in package scope resolution. - The fix reduces runtime/compile-time errors in codebases using anonymous roles and improves reliability when composing roles and packages, particularly in nested contexts. - The change is grounded in a single, well-documented commit that redefines scope semantics and prevents the error: 'Cannot declare our-scoped role inside of a role'. - Business impact: more predictable behavior for users building modular role-based code, fewer support incidents related to scope errors, and smoother adoption of anonymous roles in complex code paths. - Technical impact: reinforced understanding of Raku package scope, improved test coverage around role composition, and a clean, minimal change with clear rationale and traceability.
