Hi All, I propose that we remove the none() step from Proposal 3 ( https://github.com/apache/tinkerpop/blob/master/docs/src/dev/future/proposal-3-remove-closures.asciidoc#none). After looking into several languages that support list functions (including Groovy, Python, LINQ, and Clojure), most of them don't include a "none" function. Instead, "none" functionality is achieved through not "all". This provides a sensible way to handle an empty list as "all" would return true and "any" would return false. Given that our new approach to "all" will take a predicate in as a parameter, a user could negate the predicate to achieve the same result. Users are likely already familiar with not having access to "none" function as it probably doesn't exist in their language of choice. It's also easy to add the "none" function later if we find that users expect it to be in the language.
Please let me know what you think about removing the none() step. Thanks, Ken
