With `-wi`, it does not in fact stop:

------------------------------------------------------
$ cat test.d
import std.stdio;

void main()
{
        writeln("Hello");
        return;
        writeln("World");
}

$ dmd -wi -run test.d
test.d(7): Warning: statement is not reachable
Hello
------------------------------------------------------

Please clarify.
