Interesting Slides on Perl and concurrency

Worth reading if you are curious if Perl6 can save us from the madness and chaos that is Perl5's version of the above :)

Some interesting bits in there; looking quite similar to Future in Perl5. I recognise most of the similar bits.

Though one thing I see missing, perhaps it was just skipped over - there's no ability to "cancel" a Promise. I find that highly useful in Futures. They combine nicely using combinators as well. E.g. an "anyof" wrapper for either a task to complete or some timeout to cause a deferred failure. If the task completes we want to cancel the timer, or if the timeout happens we want to cancel the task.
