Can you elaborate on how Scala Actors don't deal well across JVMs? I thought the point of Actors was that, being about non-shared state, location wouldn't matter at all. Also, you clearly know a lot more about Erlang than I do. I'll have to catch up on the Erlang VM primitives you're referring to.

Also you'll need epmd functionality (tying Erlang nodes together) implemented. And OTP library is also missing.Qrilkahttps://www.blogger.com/profile/14856370078919907461noreply@blogger.comtag:blogger.com,1999:blog-9905395.post-91771584276506700222007-08-19T00:52:00.000-06:002007-08-19T00:52:00.000-06:00It may not be Rails, exactly, but lift looks like...It may not be Rails, exactly, but <A HREF="http://radar.oreilly.com/archives/2007/05/liftscala_for_w.html" REL="nofollow">lift </A> looks like a pretty exciting web framework.Jimhttps://www.blogger.com/profile/05992213761043927374noreply@blogger.comtag:blogger.com,1999:blog-9905395.post-72352230543245907412007-08-17T17:15:00.000-06:002007-08-17T17:15:00.000-06:00Yeah, I'm not entirely sold on Scala's syntax, alt...Yeah, I'm not entirely sold on Scala's syntax, although the ability to leave out type names the compiler can infer is a good incentive for me to get used to it. That and the ability to use first-class/higher-order functions are the specific language features that made me start paying attention. <BR/><BR/>The fact that it runs on the JVM and can use existing Java libraries is huge, though. Until someone ports Rails to Scala (only a matter of time, I feel certain), those are the killer apps.David Rupphttps://www.blogger.com/profile/16410820024654313029noreply@blogger.comtag:blogger.com,1999:blog-9905395.post-83825775734869154622007-08-17T17:06:00.000-06:002007-08-17T17:06:00.000-06:00IMHO Scala is too complicated (to learn and read),...IMHO Scala is too complicated (to learn and read), Erland excels here even compared to java.
