I'm really looking forward to watching this talk. I recently wrote a tool that uses Perl 6's Supplies to monitor directories/files and take various actions when changes are detected. By using reactive programming with Supplies, the whole program reads in a declarative way, and chains of actions can easily be modified and combined. Here's an example: https://gist.github.com/muraiki/222814d5928f648be3c1
If you've used the Reactive Extensions library across any of its various supported languages, Supplies are very similar (and IIRC were inspired by Rx). It's very powerful and I look forward to using it alongside everything else Perl 6 brings to the table, both PCA-related (for lack of a shorter term for Parallelism, Concurrency, and Asynchrony) and otherwise.
