According to Fausto Iannuzzi:

It has operator overloading; function overloading is planned but not yet
available.

This has nothing to do with OOP.

> Is there in gpc other OOP stuff that is not present in BP ?

You can mix methods and data fields:

    Type
      MyObject = object
        a: Integer;
	Constructor Foo;
	b: Real;
	Destructor Bar;
	c: Char;
	Procedure Baz;
	d: ^String;
      end (* MyObject *);

I agree.  Anybody interested to help writing such a thing?
