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.

assert( events[1]()

You can also use two lambdas to do that, without the
makeClosure:

There is a school of thought (to which I subscribe) that says
you shouldn't allocate a separate closure for each loop
iteration.
Basically, a closure will only use the stack frame of the
calling function, not any loop
