Re: Closure iterators seems to be broken or I am missing something?

I currently try to get this working. As it seems there is definitively a bug in 
Nim. But you also have a bug. You reuse `iter`. After you first calculated 
`len(iter)` iter is at it's end, and therefore consumed. But even fixing that 
doesn't bring you the result you hoped to get.
