An article titled The Essence of Google Dart, looks at some of the less discussed features. 'Snapshots' seem to bring something like Smalltalk images and allow instant startup of applications (something Java has spent the last 15 years _not_ delivering). Isolates are like OS processes and communicate with message passing — and as the article suggests, can fix the problem of Garbage Collection pauses by splitting up the heap (sounds like Erlang). There's more, mostly about feature that remove some dynamic behavior in order to make startup and code analysis easier. Maybe Google Dart's worth a second look?
