Hi,
since my reported "bug" (http://bugs.freepascal.org/view.php?id=15315) seems
to turn out to be "by design", a question came up:
are there any plans to implement class operators? In delphi they are
implemented to allow operators to affect instances of classes. This would also
enable to write operator overloads that work with generics. A good example of
that would be smartpointers. A small snippet from an example in delphi:
TSmartPointer<T: class> = record
strict private
FValue: T;
FLifetime: IInterface;
public
constructor Create(const AValue: T); overload;
class operator Implicit(const AValue: T): TSmartPointer<T>;
property Value: T read FValue;
end;
There are surely other cases where class operators would fit in nice. They
could for example allow to build something like TPersistent.Assign as :=
operator.
Is this already on a todo-list or am I out of luck here?
Thanks,
Andreas.
