Generator method to split a string using the given expression as a separator.
        May be called with optional ``maxsplit`` argument, to limit the number of splits;
        and the optional ``includeSeparators`` argument (default= ``False``), if the separating
        matching text should be included in the split results.

        Example::

            punc = oneOf(list(".,;:/-!?"))
            print(list(punc.split("This, this?, this sentence, is badly punctuated!")))

        prints::

            ['This', ' this', '', ' this sentence', ' is badly punctuated', '']
