I am curious: for some reason (no pun intended :) the `reason`s above
are not `const` except this one, but then in a later patch they become
`const` (including the declarations).

So perhaps make everything `const` when they are introduced? Or is
there some other reason? (e.g. I saw one patch that moved a function,
so there it seemed to make sense to keep things as they are to make
the copy 1:1).

Cheers,
Miguel
