Yep, I tested it before pasting it in. What I'm doing is this:

1. defining exits as a hash
2. writing a case statement to convert move from "N" or "n" or "north"
or "NORTH" to :north
3. using the converted move as a key to look up the exits hash

In the context of a larger game, you'd have a $rooms hash, with unique
identifiers like "front of building" as location keys. So you'd say

if dir
  if exits[dir]
    player.move_to(exits[dir])
  end
end

where player.move_to(location) would be defined something like

def move_to(location)
  loc = $rooms[location]
  if loc
    self.current_location = loc
  end
end
