"All COM interfaces use reference counting. This means that whenever an interface is assigned to a variable, it’s reference count is updated. Whenever the variable goes out of scope, the reference count is automatically decreased. When the reference count reaches zero, usually the instance of the class that implements the interface, is freed.”

Shouldn’t destroy be called in this example when TestScope exists?

type
	TScopeObject = class (TInterfacedObject)
		destructor Destroy; override;
	end;

destructor TScopeObject.Destroy;
begin
	writeln('dead');
	inherited Destroy;
end;

procedure TestScope;
var
	scope: TScopeObject; 
begin
	scope := TScopeObject.Create;
end;
