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:

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.
