> With the addition of (ANY|SOME) AND EVERY as an additional quantification 
> option, we no longer need to recognize different ways to specify that an 
> array is non-empty. Instead, we can just force the user to use (ANY|SOME) AND 
> EVERY.
>  
> This change should be updated in the docs, code and tests should be 
> refactored accordingly.
