Or is that not even an issue? I suppose if you are writing a LINQ statement within IR, you won't ever create an anonymous type; you would rather create a Ruby type, hash, etc. I suppose this would only be an issue if you had a method returning an anonymous type, which is already a documented no-no, so I will retract my previous question. :) Sorry for the brain-dump.
