Subject: obj.attr(qualifier) = value -- possible?


I want to write a method that can be called like this

  obj.attr(qualifier) = value

So far, I don't see how to achieve this. I've tried

class C
  def attr=(qualifier, value)
    ...
  end
end

as well as

class D
  def attr(qualifier)
    Proxy.new(self, qualifier)
  end
  class Proxy
    def =(value)
      ...
    end
  end
end

Neither is valid Ruby, apparently. Is there another, working way?

Michael
