Fun fact: Change the Link to a Tree and you go from linear to exponential in the depth. *Just* a fun fact; it doesn't change Remi's point, which is that we can construct value object instances that have large "interiors". (Definition of the day: The "interior" of a value object instance is the set of variables that determine its substitutability equality and substitutability hash.) To me this takes on a different shade of urgency when I think about turning arrays into values. Suppose we had Arrays.valueCopyOf to take an immutable value-typed snapshot of an array. Very useful! (Sort of like frozen arrays.) You can make a size 1_000 value-array very quickly and easily, and its interior would be as large as Remi's laboriously constructed list.
