What is the correct way of making this output `0 1 2`?

```d
void delegate()[] dgs;

foreach (immutable i; 0..3)
{
    dgs ~= () => writeln(i);
}

foreach (dg; dgs)
{
    dg();  // outputs: `2 2 2`
}
```

You have to do it like this:

```
dgs ~= ( (n) => () { writeln(n); })(i);
```

Because D hasn't fixed their million dollar mistake after so many years:
