    r"""
    Performs multiple replace functions foreach item in search_list and
    repl_list.

    Args:

        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:

        >>> from utool.util_str import *  # NOQA
        >>> 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)
