def extract(_field_name, object, local_options, options = {})
  block = options[:block]

  # Symbol#to_proc creates procs with signature [[:req], [:rest]]
  # These procs forward ALL arguments to the method, which causes
  # issues when we call block.call(object, local_options) because
  # it becomes object.method_name(local_options), and most methods
  # don't accept extra arguments.
  #
  # For Symbol#to_proc, we only pass the object.
  # For regular blocks, we pass both object and local_options.
