class_docstr: For Lua source code.
  
  Additional options accepted:
  
  `func_name_highlighting`
      If given and ``True``, highlight builtin function names
      (default: ``True``).
  `disabled_modules`
      If given, must be a list of module names whose function names
      should not be highlighted. By default all modules are highlighted.
  
      To get a list of allowed modules have a look into the
      `_lua_builtins` module:
  
      .. sourcecode:: pycon
  
          >>> from pygments.lexers._lua_builtins import MODULES
          >>> MODULES.keys()
          ['string', 'coroutine', 'modules', 'io', 'basic', ...]
