Local variable inside delegate literal

[Daniel]

I'm writing some gui code, and am currently trying to make something equivalent 
to this:

int delegate()[] funcs;
funcs.length = 3;

foreach(i, ref f; funcs)
{
  f = int() { return i; }
}

foreach(f; funcs)
{
  writeln(f());
}

Prints:
3
3
3

I want it to print
0
1
2

Is there anyway to get this behaviour using delegate literals initialized with 
a runtime loop?
