} But you don't know which one:
}
} $ for i in 1 2; do /bin/false $i; done
} zsh: exit 1 /bin/false $i
} zsh: exit 1 /bin/false $i
eval "veryimportanttask ${(b)i}"
Of course then printexitvalue prints "exit 1" for each of the eval
as well. *There* is a case where it's probably entirely extraneous.
torch% setopt printexitvalue
torch% for i in 1 2; do eval /bin/false $i; done
zsh: exit 1 /bin/false 1
zsh: exit 1
zsh: exit 1 /bin/false 2
zsh: exit 1
