The compiler already has all the plumbing for implementing this but they
would need to agree to a new class type which includes has the same ref
counting as AnsiString, Interfaces and other types. I mentioned this
multiple times but Sven objected to it stating he already tried and
uncounted some edge cases.
I think an entirely new class type would be required and that’s where the
resistance came from. Sven can refresh us on this if he wants.
