null_value(x)

show_fit(model, eng)

check_args(object)

new_model_spec(
  cls,
  args,

  mode,
  user_specified_mode = TRUE,
  method,
  engine,
  user_specified_engine = TRUE
)

check_final_param(x)

update_main_parameters(args, param)

update_engine_parameters(eng_args, fresh, ...)

print_model_spec(x, cls = class(x)[1], desc = get_model_desc(cls), ...)

update_spec(object, parameters, args_enquo_list, fresh, cls, ...)
