def self.matches_all(attributes, to_check, &block)
  # "Zeroth" case: attributes is nil
  return true unless attributes

  # First case: there's a single negated attribute
  if attributes.is_a? Negated
    # The contained object might also be an array, so recursively call matches_all (and negate the result)
    return !matches_all(attributes.object, to_check, &block)

  # Second case: there's a single, not-negated attribute
  return yield(attributes, to_check) unless attributes.is_a? Array

  # Third case: it's an array of attributes
  attributes.reduce(false) do |result, element|
