Awesome! I'm wondering whether using jQuery's deferreds can give close to same advantages.

Looking at first parallelSearch example, it could be like that (in regular CoffeeScript):

  parallelSearch = (keywords, cb) ->
    searches = [search k for k in keywords]
    $.when.apply(searches, null).then cb

Although seems like it can't really cover all Iced's use cases. Hopefully the fork will continue to be maintained!
