def falsey?(value)
  !value ||
    (value.respond_to?(:to_ary) && value.to_ary.empty?) ||
    (value.respond_to?(:to_hash) && value.to_hash.empty?) ||
    (value.respond_to?(:to_str) && value.to_str.empty?) ||
    (value.respond_to?(:entries) && !value.entries.any?)
  # final case necessary to support Enumerable and Struct
