Well, I'm sure it's possible to do something that would react like 
this :

class Foo
	abstract :bar, :baz
end

class Quux < Foo
	def bar()
		puts "Hello."
	end
end

q = Quux.new()
q.bar
=> "Hello"
q.baz
=> exception "Baz must be implemented in child."

Now, is that useful, pretty, ruby'ish, and whatever, I don't know.

And it's limited to methods (and / or accessors ?).
