Is there a particular reason why "+" makes more sense as "shallow
concatination" and "||" makes more sense as "deep concatination"? Like,
something in JS or other client languages which would make that
preference make more sense to users?
While I hate last-minute changes in general, once we have this
functionality as || we won't be able to swap operators later if we
decide that deep concatination should have been ||. So I want to be
clear on why users will prefer that to + .
