Don't get confused by 'new' in struct initializers. Structs in C# are
value types.
Yes, you are right.
But in D structs can be allocated on the heap too, so I think having
optional nonnull struct pointers can be useful. The syntax and usage is
similar to normal struct pointers.
I don't know why a struct pointer would be different than any other
pointer. That is, you'd have S* and S*? as well as int* and int*?.
Note that C stdlib (and other libraries/bindings) will need to be updated
to reflect changes, e.g.
extern(C) void*? malloc(size_t size); // may return null!
which is great because it will provide additional safety. I've seen quite
a lot of code that don't test returned value against null (which is a
mistake, I believe).
