* commands: any? all? We can check if `any` (or `all`) rows of tables match predicates. Small `all?` example: Given the following table with `services` running: ``` > echo [[status]; [UP] [UP]] ───┬──────── # │ status ───┼──────── 0 │ UP 1 │ UP ───┴──────── ``` We can ask if all services are UP, like so: ``` > echo [[status]; [UP] [UP]] | all? status == UP true ``` * Fix any? signature.
