You could test equality after Marshalling ? On closures, it should compare code address
and the values in the closure. This does not give extentionnal equality (which is impossible), but an
intentional equality which is sometimes meaningful. I am wondering why this is not the default
for = or at least why the is not a way to choose like in the marshall module.
