I have an objective reason to prefer one over the other.  Your only
reason is consistency.  If consistency was everything, we might as well
let the often-abused 1000 monkeys type up a coding style document and
stick to that.

But most of our rules exist for reasons beyond mere consistency.
Following the rules, on average, makes the code better.  In particular
the "less" rules (fewer lines, less indentation, etc.) result in more
code fitting any arbitrary editor window.  Which means more control flow
our mind can ponder about without scrolling.

Do you have a non-consistency based reason to prefer the longer version?
If not, then we should settle on the short version, which does have a
minimal advantage.
