> the rule looks perfectly sensical to me. If I change it to this (which, btw. looks non-sensical)
> wine : Wine(color == "red")

>             person : Person(height == 13, fovouriteCheese == cheese)
>         )

> I'm not saying the second one shouldn't work(I fail to make the sense of it however), but it looks to me, the first one should.
