 Review comment:
   Please ensure there is a newline at the end of the file. An easy way to check for this is to run the below from repo root:
   ```
   find . -type f -a -not -regex '.*/[.]git/.*' -exec grep -Iq . {} \; -print0 | xargs -0 -L 1 bash -c 'test "$(tail -
   c 1 "$0")" && echo "No new line at end of $0"'
   ```
