I agree it's not the cleanest, but it's not like I would be adding any feature. rubyspec doesn't give me any addition error, expect the one that explicitly tests for the exception. What I'm more worried about, is if other ruby implementations can come up with a working solution. For example if instance variables are transformed into an array index at compile-time (rubinius?), then the index might not be the same in the other object.
