Subject: method_missing question

Can someone complete the psuedo-code in SomeObject#method_missing for
me?  Or suggest a better way of doing this?  The attributes for
SomeObject are, in my application, are generated from a configuration
file.

Thanks
Joe

class SomeObject
    def initialize
        @attributes = { :x_pos => 20, :y_pos => 30, :z_pos => 40 }
    end

    def method_missing(method, *args)
        # test to see if this is a get or set method
        if method contains an =
            set(method minus the equal, args)
        else
            get(method)
        end
    end

    def get(attribute)
        @attributes[attribute]
    end

    def set(attribute, value)
        @attributes[attribute] = value
    end
end

my_obj = SomeObject.new
my_obj.x_pos = 20
my_obj.z_pos = 40

assert(20, my_obj.x_pos)
assert(40, my_obj.z_pos)
