Btw, what I have meant originally is that if built-in attributes 
where provided by some runtime module similar to object.d 
(instead of being part of grammar), one could use specialized 
imports at module top-level to prioritize them over built-in ones 
and make transition trivial:
```
import myudamodule : property;

// ...

@property // explicit symbol import has higher priority over 
normal one, no name clash
void foo() {}
```
