We tried this once before and came to the conclusion it couldn't be
done, if I recall correctly. The problem is you can't access the
current
index of the list from inside a comprehension(or a map(), filter()
etc)

I think an explicit loop is the only solution for this type of
operation in versions prior to 2.3.
