For the program you've written, I'm happy it doesn't compile, 
because a lot of the time the compiler would be making buggy code 
compile - though I would love to have a way to do it explicitly. 
In this case you can change your definition of None to use alias 
this and it will compile:

```
struct None {
    alias convert this;

    Option!int convert() {
        return Option!int(None());
    }
}
```
