would be nice to use alias this as struct inheritance substitute, 
especially in conjunction with Implements!()

But maybe I don't get the "alias this" thingy. So what's my mistake > TIA

sorry

Struct is value type, not reference type like class. You don't need 
'new' to create it, just uncomment your constructor ('this') and remove 
'new':

point3D p3 = point3D(10,20,30);

If you really need to allocate a point on the heap, then you'd have to 
use pointers:

point3D* p3 = new point3D(10,20,30);

Though you probably wouldn't need that much.
