I appreciate the thought, but it kind of doesn't matter what I might
want. I have to stick with the crap I'm building on because I don't
feel like rewriting a gem.

In case anyone is wondering, the 'solution' (as in it works but I
don't recommend it) with help from Aaron "tenderlove" Patterson, goes
something like this.

    Thing = Struct.new(:a, :b, :c) do
      def some_thing
      end
    end

    class Thing
      attr_accessor :d

      alias_method :old_brackets, :[]
      def [](m)
        if m.to_s == 'd'
          self.d
        else
          old_brackets(m)
        end
      end

      alias_method :old_brackets_equal, :[]=
      def []=(m, v)
        if m.to_s == 'd'
          self.d = v
        else
          old_brackets_equal(m, v)
        end
      end
    end

Tell me that doesn't make you unhappy.
