The title mentions Futures & Promises, but the link is directly to the GitHub project without any further information about those concurrency constructs.<p>I'm curious if they managed to implement the blocking operations of Future [1], such as the "result" method. And, if so, did they accomplish that using the same Continuation Passing Style transform that Scala's Delimited Continuations [2] plugin uses, or some other means?<p>[1]: <a href="http://www.scala-lang.org/files/archive/nightly/docs/library/index.html#scala.concurrent.Future" rel="nofollow">http://www.scala-lang.org/files/archive/nightly/docs/library...</a><p>[2]: <a href="http://www.scala-lang.org/api/current/index.html#scala.util.continuations.package" rel="nofollow">http://www.scala-lang.org/api/current/index.html#scala.util....</a>
