I didn't make the distinction, the post sort of did between the lines. Go back to my original comment and you'll see that multiple dispatch is what got us here. I never said anything about mutable/immutable data, I'm talking about polymorphism. But I did mention type classes as an alternative. I frankly fail to see how this is leading anywhere.
