Rename `all?`, `any?` and `empty?` to `all`, `any` and `is-empty` for sake of simplicity and consistency. - More understandable for newcomers, that these commands are no special to others. - `?` syntax did not really aprove readability. For me it made it worse. - We can reserve `?` syntax for any other nushell feature.
