I've run across this myself. The workaround I used was to call a
function from inside the foreach loop, and in that function you
construct the delegate (with the index variable passed as a
parameter).
Hah, sorry, I didn't read the last post. I did exactly what Ali
just suggested.

Is there a function in phobos that lets me do something like
DateTime.format(MM:DD: ) with a DateTime instance?
delegate has a context pointer that it uses when executing
at run-time. However, there can't be a run-time context of a
delegate that is created at compile-time. I think that is why
the segfault.
Is there a reason why it needs to be a delegate?
Replacing every 'delegate' with 'function'

Is it possible to override std tuple's toString format?
so that
