DIP1000: Scoped Pointers (Discussion)

[Robert burner Schadek via Digitalmars-d]

```
void foo() {
     int c;

     ....
     int* e;
     e = &c; // Error, lifetime(e's view) is ∞ and is 
greater than lifetime(c)
}
```

The DIP should make clear that this is wanted for a container 
library.
Additionally, I miss how this DIP fits in the overall plan of 
getting rid of the GC. As long as there isn't a written 
masterplan how to combine those ideas I consider this DIP to be 
incomplete.

I think this change is not worth it. I believe there is an 
inherent trade-off for every programming language between 
usability and theoretically correctness. And IMO this DIP is 
pushing D way to far in the direction of theoretically 
correctness. There are far more important things for the adoption 
of D, like making the frontend a library, shipping with multiple 
backends.
