And whether they *can* work. D2 has struct constructors, so structs can 
have non-nullable fields, but you can't have an array of non-nullable 
elements (you can set the length, and suddenly your non-nullable-element 
array has a bunch of nulls in it). Similarly, no arrays of structs 
containing non-nullable types, etc.

There are a lot of things to look into with non-nullables, and Walter 
doesn't have the time.
