Compete to write the fastest function implementations!

1. Click on a time in the table below to view the current record implementation.
2. To compete, implement the function in the corresponding function.lang file. No code is allowed outside the function.
3. Make a PR. A GitHub Action will benchmark and verify your code, and if it's a new record, you'll be added to the leaderboard for that function!
