This was suggested by Niklas [1] to make the conditionally compiled code
more readable. The alternative would be masking out the code with a big
`#ifdef`.

If you prefer the latter, I can change it back, no problem. But I must
say I think it comes off cleaner when we move as much as possible of the
zoned code to a separate translation unit.
