Subject: understanding continuations


rubyists-

i am trying to grok continuations, and only barely understand them.

my goal is to implement an Enumerable#next method which uses
Enumerable#each_with_index and callcc.  i have one or two ways which work, but
recurse infinitely.... my main problem is how to know when each_with_index is
on the last item!  however, i really don't understand what i'm doing!  if
anyone can provide more insight into continuations than the pickaxe, i'd
appreciate it.
