Is there a good way to produce the remainder of a deal?

Options:

Status quo

@map_function
def my_function(hand):
  remainder = initial_deck - hand
  x = remainder.deal(3)
  # ...

result = my_function(deck.deal(5))

Ellipsis

Use ... to represent the remaining cards.

hand_and_remainder = deck.deal(5, ...)

This doesn't play great with map_function, unless we allow arguments to take multiple slots. Also, presumably the user would have to cast the remainder back to a Deck:

@map_function
def my_function(hand, remainder):
  remainder = Deck(remainder)
  x = remainder.deal(3)
  # ...

result = my_function(deck.deal(5, ...))
