Apparently, along the way of building AgileWiki, the main author decided to do some work on actors in Scala. [that page has a toc that goes to other pages, that isn't the whole document on one page.] I guess because there just aren't enough, what with the original Scala actors library, the Akka library. But in particular this vein is about figuring out how to blend shared state (actor mail boxes) when things are sufficiently ascynchronous vs. when to avoid shared state when things are synchronous. It feels in a distant hand-wavy way in my head like there's some E-lang vat-ness about offering a mix of async and blocking. If some day it was all automagically being configured properly for me dynamically at run-time, that might be cool.
