I like OOP so I'd tend towards that, but the second suggestion,...

  shuffled_deck = shuffle(deck)

is okay too. Global variables, like GOTO, can easily be misused and cause
weird bugs. Its a bit unfortunate that Euphoria encourages them, but until
namespace and forward referencing issues are finalized, we have to live with
this little "devil".

Also, the function method makes it easier to implement non-standard decks
(short or enlarged ones, for example.).

   shuffled_deck = shuffle(deck & deck)

   shuffled_deck = shuffle(deck[Spade04 .. SpadeAce] & deck[Club04 ..
ClubAce])
