Look how easy it is to build a deck of cards in Elixir! Example shamelessly taken from "Programming Elixir", which you should definitely buy

import Enum

# build a deck of cards
deck = lc rank inlist '23456789TJQKA', suit inlist 'CDHS', do: [suit, rank]
# -> ['C2', 'D2', 'H2', 'S2', 'C3', 'D3', ... ]

# take 5 random cards from the deck
hand = deck |> shuffle |> take(5)
# -> ['D8', 'CQ', 'H2', 'H3', 'HK']

# split the deck into hands of 5
hands = deck |> shuffle |> chunks(5)
# -> [['DQ', 'S6', 'HJ', 'H4', 'C7'], ['D6', 'SJ', 'S9', 'D7', 'HA'],
#     ['S4', 'C2', 'CT', 'C8', 'C3'], ['D3', 'C5', 'C6', 'C4', 'SQ'],
#     ['S2', 'SA', 'DJ', 'D8', 'SK'], ['H5', 'ST', 'CK', 'D5', 'H2'],
#     ['CA', 'DT', 'HQ', 'CQ', 'S7'], ['HT', 'S3', 'H7', 'H6', 'H9'],
#     ['H8', 'D9', 'C9', 'HK', 'S8'], ['H3', 'D2', 'DA', 'CJ', 'S5']]
