`none()` would work as follows:

```julia
none([false, false, true, false]) => false
none([false, false, false, false]) => true

```

`!any` is the same length as `none` and already works…

IMHO `none` would be much more clear when reading code… but I agree we can also live with `!any`.

Agreed – it’d give use the full set: `any`, `all`, and finally `none`.

Easy fix where you want to use it:

```julia
const none = !any

```
