Right.

We have similar methods on C++ in the class VLink2

Keep in mind:

    Vlink -- this is general class of Vlink.
            future we can have Link_N which links N tables.

    VLink2 -- is subclass of Vlink and is parent of 3 links:
                FK, ObjectPtr and BinaryLink.

In VLink2 we can introduce set of methods that have SIMPLER syntax than
Vlink methods. Right. Just was no time to finish this job ...
