We'll need to be very careful with this line of thinking:

```d
scope {
	void func() {
	}
}

scope:

void func2() {
}
```

Doing stuff like this is good, and useful.
I use it, a lot.

Explicitly stating that final will bind to the function declaration, not 
its this pointer is required.

Really the only way to get out of this is to use different keywords.
