About the null references, most people seem to agree that the right way to fix that is with some sort of "non-nullable". But there's a lot of disagreement on exactly how non-nullables should work.
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.
