Real nullable types will probably never make it to the language, but wel can still dream

Posted by jpluimers on 2016/10/06

Allen Bauer (ex Delphi R&D team) wrote the brilliant piece about a year and a half ago. We can still dream, right?

Allen Bauer, May 25, 2015

Current working theory of Nullable<T>.

Nullable<T> = record
…
property Value: T read FValue; default;
…
end;

Using the default directive to “hoist” the operators of “T“. Currently the default directive only works for array properties by “hoisting” the ‘[]‘ operator. Marking a non-array property with default will make the containing type behave as that type.

This, coupled with some intrinsic compiler knowledge of the Nullable<T> type will make Nullable<T> work without any addition of keywords or other standard functions or procedures.

Using the “default” directive on a non-array property will work for any type, except for having the null-propagation semantics.

When considering language features, I try and not only make it work for the intended purpose, but also broaden reach of any supporting feature. In the above scenario, even user-defined operators on “T” will be properly hoisted and used.

This was part of a very interesting G+discussion at Delphi’s New Feature Desired: Nullable Types and Null Propagation….

It covered topics like these:
