Re: copying arrays

In my experience it's quite rare to have to have to *copy* a
sequence. If you're manipulating an array, why would you want to
retain the previous version?

In a game, you might want to pass the state of the game
(e.g. the board in a board game) to a computer player
so it can decide what it wants to do. The safe way to do that
would be to pass the player a copy, so the player doesn't
corrupt the game. Often the player will destructively modify
the board, but undo all its changes at the end. With a copy,
you can also check the player for correctness by comparing
the final state of the player's copy with the original board.
