Oh ok, fair enough, thanks. Shows how much I know :) I’d never seen it before.

This `??` operator seems a bit unique to vim9script. If we're trying to be

considering the feedback I have received, it's not very consistent and
has a few surprising sides.
One thing is that the "||" and "&&" operators do not result in a boolean
true or false, but the argument value. This is nice for som
