Thanx.

One of the things I don't understand are the semicolons. When I read the 
Book, it said:

class SomeThing
  atrr_reader :x, :y
end

I figured out that the attr_reader need to get the name of the instance 
variables.

However, what is this code good for?

 def make_point_hash( point )
   center = { :x => 1, :y => 2 }
   big = { :r => 10 }
   center.merge( big ).merge( point ) 
 end
 make_point_hash( { :x => 20 } )

 #=> {:y=>2, :r=>10, :x=>20}

What is that those semicolons do?
