Probably slightly off topic, but be very careful with operator overloads  
without using constraints.

For example, I can do some weird things to your struct:

Point p;

p.opOpAssign!"*x; y+="(5);

I suspect operator overloads are going to be a large hole in the interface  
design of many objects, but at least they won't be exploitable once  
compiled.
