I remember reading this was an issue and now I ran into it 
myself.

```d
import std.stdio;

void main()
{
    auto names = [ "foo", "bar", "baz" ];
    void delegate()[] dgs;

    foreach (name; names)
    {
        dgs ~= () => writeln(name);
    }

    foreach (dg; dgs)
    {
        dg();
    }
}
```

Expected output: `foo`, `bar`, `baz`
Actual output:   `baz`, `baz`, `baz`



For c# reference when they fixed it:

To have a way out for old behavior by capture reference,
from:  dgs ~= () => writeln(name);
to:  dgs ~= () => writeln(&name);
