@rebolyte thanks for your PR- the change itself looks good to me but your git config needs a little tweak. Can you run the following command to set your email in your git config:
git config user.email "MY_NAME@example.com"

Then run git commit --amend --reset-author and push again
This is so that you're credited correctly for this PR (for instance, your github badge will change from "First time contributor" to "Contributor" once this PR lands if your email is correct)

(thanks to @gireeshpunthil for this tip!)

@digitalinfinity Thanks for the heads-up! I had a different email in my git config. Pushed with the new correct one.

@rebolyte Do you think you could rebase this against master? There’s a merge commit in here, and that doesn’t play too well with our CI…

I'll put together another PR later on that combines most of the open Code & Learn tasks and I will also resolve the merge in that case and run the CI on those before landing. I'll add the author-ready label due to that.
