You're not too late for the CPAN Pull Request Challenge
The CPAN Pull Request Challenge has now been running for half a year. Hundreds of people have done pull requests on CPAN distributions. Many have fallen by the wayside, as life and other distractions caught up with them, but more than 50 are still in the game. If you haven't tried it yet, it's not too late — you can sign up any time before 31st December.
