If you need to detect syntax issues, you can use `re.compile()`. For example, before Python 3.11, you'll get an error:

    >>> re.compile(r'\w++')
    re.error: multiple repeat at position 3

To use such a compiled pattern, you can call the method on this object instead of `re`. For example:

    >>> word = re.compile(r'\w+')
    >>> word.findall('hello-there!')
    ['hello', 'there']
