The init value of `Nullable!(Node!string)` is an object with two member fields - `value` of type `string` and `next` of type `Nullable!(Node!string)`. The default constructor modifies neither, so they will both remain with their initial values. The init value of `string` is an empty string. What is the init value of `Nullable!(Node!string)`? To find the answer, return to the beginning of this paragraph and read it again.
I made a mistake here - `Nullable!(Node!string)` is a struct with a boolean member `_isNull` and a `Node!string` member named `_value` which is an object as described in this paragraph. Still, the point remains - even if `_isNull` is true, `_value` still need to refer to a `Node!string` object.
