This is a super-minor style point, but if you write these one-liners as
Scaladoc then they'll show up in the quick documentation popups in IntelliJ. I
don't feel super strongly about this and we haven't been consistent about this
throughout Spark, but just thought I'd comment since this has been on my mind
lately.
