delegates with references to local strings

[Tobias Pankrath]

consider this:

------------
import std.stdio;
import std.string;

alias void delegate() dlgt;

int main()
{
        dlgt[] dgs;
        string[] lines = ["line A", "line B", "line C"];
        foreach(line; lines)
        {
                writeln(line);
                dgs ~=  { writeln(line); };
        }

        foreach(dg; dgs) { dg(); }
        return 0;
}

-----------

It prints every line in line and stores a delegate that does the 
same.
The output is:

line A
line B
line C
line C
line C
line C

I want it to print every line twice. How can I store the string 
of the current iteration with a delegate? I tried dup'ing into a 
local, which didn't help.

Thank you for your advice.
