                             Group

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

Example:

       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']]
