Hi,
Say you have a method in a class that's defined as this:
(working from Peter Cooper's Beginning Ruby book, p. 155 of the book)

class Dungeon
.
.
.

def start(location)
@player.location = location
show_current_description
end

why is it that when you place the player in the large cave, it's
my_dungeon.start(:largecave)

instead of
my_dungeon.start(largecave)
?
why is largecave a symbol?
Thanks so much!
