Though Ruby 2.3 introduces `&.`, but this can���t be written as `ary&.empty?`. One idea is add `nonempty?` write as `ary&.nonempty?`. akr: `nonempty?` is not good name because human is not good at handling This discussion matches following core classes: * String * Array * Hash -- https://bugs.ruby-lang.org/ Unsubscribe:
