docs: 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', '']
