# CPAN

13 Hacker News commenters recommended CPAN and 10 criticized it, November 2025 to November 2026. It was recommended in 6 of 13 months.

**Verdict:** Pioneering Perl module repository that made reusable libraries easy to share, and helped shape package management. Critics say module quality was uneven and dependencies could conflict.
