Ok, I understand what you mean now. This is actually a really great idea for
all sorts of other uses because it helps to unify namespaces between classes
and prevent long.and.annoying() chaining of fields.
Btw why should this be a property? I know [] properties use the default keyword
also but I don’t understand where this came from and it’s strange to name the
[] property since the name is irrelevant. I would think you’d want to just put
a modifier on the default field:
TAutoCreate<T: class> = record
_: T; default;
class operator Initialize(var a: TAutoCreate<T>);
class operator Finalize(var a: TAutoCreate<T>);
class operator Copy(constref a: TAutoCreate<T>; var b: TAutoCreate<T>);
class operator AddRef(var a: TAutoCreate<T>);
end;
just curious and I thought I’d ask.
