Another feature that would be interesting is if an `auto` 
declaration stripped const/immutable where possible. After all, 
if the user didn't want that they could've used `const` or 
`immutable`.

```d
const i = 4; // const int
auto v = i;  // int
const a = [0]; // const(int[])
auto s = a;    // const(int)[]
```
