Subject: Is possible to extend "attr_accessor" "attribue=" method?

Hi, I'd like to use an "attr_accessor" but when its attribute is
modified it should be executed more code than just an assignament.
I handle it in this way (not cool):

	class MyClass1 < Father
		
		attr_reader :my_param
		
		def  my_param= (value)
			@my_param = value
			@modified = true
			...more code...
		end
	
	end


As you see I can't use "attr_accessor :my_param" since if I use it I
should also redefine "my_param=" method.
I have lots of MyClassX classes inheriting from "Father" and I'want
@modified to be an attribute of Father and each soon class has its own
attributes, and when any attribute is modified I want @modified to
become true, so I'm looking for something as:


	class Father
		
		# Attributes: @modified (false by default)
		
		def **any_attribute**= (value)
			@**ny_attribute** = value
			@modified = true
		end

	end

	class MyClass1 < Father
		attr_accessor :my_param1, :my_param2
	end


Is it possible in saome way? mybe using "no_method_name" method?
