Jan 1, 2026January 2026 — Perl/perl5: Enhanced control character variable handling and diagnostics. Delivered a feature that wraps multi-character control character variable names in braces to produce ${^FOO}, corrected representation for control character variables starting with _, and ensured EBCDIC-compatible handling in the diagnostic path. This improves diagnostic clarity, correctness of variable representation, and cross-encoding portability. GH-24135-driven enhancement with collaboration from Karl Williamson.
