Oh wow. Had no idea there was no inlining. That is potentially another 2-3x performance.

To be slightly more correct, there is inlining but only of trivial methods that simply return an immediate value or a constant, e.g.

    class NilClass
      def blank?
        true
      end

      def present?
        false
      end
    end
