Ну, всё же оно не настолько забавное
На самом деле конструкции языка довольно классические, есть даже что-то интересное. Например:

> Nullable TypesСобственно дока по языку тут: Types may be nullable or non-nullable. A non-nullable type is guaranteed to never store the null value. Nullable types are indicated with a trailing "?". This means non-nullable is the default unless otherwise specified:The compiler prevents obvious mistakes like using the null literal when a non-nullable type is expected. Additional checks are implicitly done at runtime when coercing a nullable type to a non-nullable type. This allows your code to fail fast at the point where null bug was introduced versus propagating into unrelated code.
