def process_inline!(mod, definition)
  _name = definition.name
  mod.instance_eval do
    @_name = _name.singularize.camelize
    # this adds Form::name for AM::Validations and I18N.
    # i have a feeling that this is also needed for Rails autoloader, which is scary.
    # beside that, it is a nice way for debugging to find out which anonymous form class you're working on:
    #   anonymous_nested_form.class.name
    def name
      @_name
    end
