         TokenConverter --+

Converter to return the matched tokens as a list - useful for returning tokens of :class:`ZeroOrMore` and :class:`OneOrMore` expressions.


   ident = Word(alphas)
   num = Word(nums)
   term = ident | num
   func = ident + Optional(delimitedList(term))
   print(func.parseString("fn a, b, 100"))  # -> ['fn', 'a', 'b', '100']

   func = ident + Group(Optional(delimitedList(term)))
   print(func.parseString("fn a, b, 100"))  # -> ['fn', ['a', 'b', '100']]
