…ing (in object creation)

So we can write:
```python
def createScene(root):
	root.addObject("MechanicalObject", name="loader", filename="mesh/cube.obj")
	root.addObject("MechanicalObject", name="dofs", position=root.loader.position)        # to make a link
	root.addObject("MechanicalObject", name="dofs", position=root.loader.position.value)  # to make a copy by value
```

…ring

Because it breaks bckward compatibility and was not really better.

So we can write:
object.position.link instead of object.position.getLinkPath()

Which will make the syntax a bit more compact.
