module method with options before declaring module_function Errors out

[gkellogg]

Try creating a directory 'lib', and then add the following as the contents in a file called 'test.rb' within lib:

module Test
  # @param [#to_s] arg
  # @param [Hash{Symbol => Object}] options
  # @option options [#to_sym] :format
  def test(arg, options = {})
  end
  module_function :test

end

This errors out with the following:

If you remove the @option, the problem goes away. My investigation made it look like there is an @option with a nil text element that is being processed when the module_function is hit.
