If you want to iterate over several iterables together, that's what
izip is for..
forEach(izip(togglers, stretchers), function (lst) { lst[0].stretcher
= lst[1]; });
If you want an index, you could izip with count()... but in general
you really shouldn't care much about indices when you're iterating,
at least in a functional style.
