      Args:
          str_ (str): string to search
          search_list (list): list of search strings
          repl_list (list or str): one or multiple replace strings
  
      Returns:
          str: str_
  
      CommandLine:
          python -m utool.util_str --exec-multi_replace
  
      Example:
          >>> # ENABLE_DOCTEST

          >>> str_ = 'foo. bar: baz; spam-eggs --- eggs+spam'
          >>> search_list = ['.', ':', '---']
          >>> repl_list = '@'
          >>> str_ = multi_replace(str_, search_list, repl_list)
          >>> result = ('str_ = %s' % (str(str_),))
          >>> print(result)
          str_ = foo@ bar@ baz; spam-eggs @ eggs+spam
