I think this PR is ready to get a review.
And not sure of what base branch this PR goes to? master? 10.1_release?

This looks great thanks.
Would you add a couple of tests for pattern matching analogous to those for records with optional fields.

This looks finished to me.
I think it could go into 10.1 as it's a low-risk change and replaces a type error that surprises users anyway.
If we go with 10.1, this should be based on that branch.
And once the PR is merged, then branch 10.1 should be merged into master again so this last PR is added.

Pre-existing, but these @ns.optional in the file above here are unnecessary since there's proper syntax for that.

There were too many conflicts to rebase to 10.1_release, then I cherry-picked.
During cherry-picking, there was a conflict in the change log, I mistakenly merge the latest change logs from master. So I removed it in 95f47f9

Now it is rebased to the 10.1_release.
