Delphi also allows skipping the ^ for e.g. pointers to records. A
difference is that it does not allow using ^ at all for classes, but
Also, in Delphi (and in FPC's Delphi mode) untyped pointers can be
automatically converted by the compiler into class types, so they are
quite close. I don't really see a big advantage in changing the
encoding of class types in the debug information, especially since
even now stuff like classinstance.fieldname works.
