Similar to a Java Optional<T> [1]

Give it an interface that allows you to attach behaviours for not null and null values.

Function passing/callbacks, no thanks. You still won't get a compiler error when passing a potentially nil value, and I'd rather have readable code. I hope Optional is not going to be in the way of progress in this area.
