This made me realize you *can* force the compiler to throw an 
error rather than initializing variables:

```
import std;

void main() {
     MyDouble z = 1.0;
     writeln(z);
}

struct MyDouble {
     double x;
     alias this = x;

     @disable this();

     this(double _x) {
         x = _x;
     }
}
```

The same can be done to prevent ugly bugs like we discussed in an 
earlier thread:

```
struct Foo {
     struct Bar {
         double x;
     }
     Bar bar;

     @disable this();

     alias this = bar;
}

// Neither line will compile now
void main() {
   Foo foo;
   auto foo = new Foo;
}
