The general idea is that in the core language, we deliberately do not follow any particular code style, so as to demonstrate (by leading by example) that whitespace is not relevant and that the Standard takes no position on formatting.

The library uses a consistent style for its own content, but that's a different matter.

Ah ok, I was familiar with the policy but didn't know it was taken to this extreme to deliberately advertise poor style. I guess properly indented example code will remain an eel.is/c++draft killer feature that's unavailable in the PDF. ;)
