Documentation
parseRegex :: String -> Either ParseError (Pattern, (GroupIndex, DoPa)) #
Return either an error message or a tuple of the Pattern and the
 largest group index and the largest DoPa index (both have smallest
 index of 1).  Since the regular expression is supplied as [Char] it
 automatically supports unicode and \NUL characters.
