You can implement coroutines with continuations with two functions:

    def resume
      callcc do |cc|
        $current = self
        @caller = cc
        @resumer.call
      end
    end
    
    def self.yield
      callcc do |cc|
        $current.resumer = cc
        $current.caller.call(cc)
      end
    end

`resume` (on a coro) will store what coroutine we're entering (globally) and the caller-continuation (so we know where to go to after Coro.yield). It will then invoke the `resumer`-continuation. `Coro.yield` will store the `resumer`-continuation on the coro (so we know where to go to after `.resume`).

You need something to kick it off though. The simplest way is probably to use `(@resumer || @code).call`.

Nice! I've already given my invites away though, sorry :(

In CoffeeScipt-flavored pseudocode, I'd say

    memoize (f): ->
        cache = { }
        () ->
            h = hash arguments
            cache [h] ? (cache [h] = (f arguments))

And my email would be my username at most popular email service dot com.

I don't know CoffeeScript too well, but reading as pseudo-code looks good.

What email do you want me to use?

Thanks.

sent!

Just received it, thank you.

memoization, basically remember the results of methods that have a particular parameter values. so it does not actually execute the method it retrieves the remembered value

I still have 1 invite so if you give me your email I'll give it to you.

IOW, memoization is a pretentious way of saying result caching.

You replied 3rd and this was already answered, but I don't think anyone is going to answer the continuation question.

So I'll give it to you. What email do you want?

I would love to try my luck :) Or a charity for my cause :) Mohsen@ozaibi.com Me@ozident.com Hope it's not too much to ask :) Cheers

What email do you want? :D

emailed it to you
