The issue is that methods can be called from outside the object. Then, we can build around the Entity type to create things like generic HTTP handlers. cdecl; but omit this directive in the implementation, or vice versa. Records have no inheritance and therefore non static class methods have no sence for them.

Sending a message to super is a way to call through to a method implementation defined by a superclass further up the inheritance chain. Error: 32 Bit-Integer or pointer variable expected The libbase for MorphOS/AmigaOS can be given only as longint, dword or any pointer variable. Error: Only one default property is allowed You specified a property as Default, but the class already has a default property, and a class can have only one default property.

Well, understanding how interfaces are represented in memory makes some potentially confusing things very obvious.
