Very interesting talk! Thanks for the reference.

More food for thought:

The style in your example is more consistent with the way nearly every programmer formats code that has more than one statement. For example:

  if( shouldDoThings ) {
      doOneThing();
      doAnotherThing();
      doLastThing();
  }

Why do we want to format statements that way, but function calls and expressions a different way? No one would write this:

  if (shouldDoThings) {doOneThing();
                       doAnotherThing();
                       doLastThing();}

I have a theory about that but will have to save it for another day.

Somewhat related, the Rust coding style guidelines used to follow a heavily column-aligned style, but changed to indentation-only a year or two ago. I posted an example from the Servo source code with the old and new formats here:
