(as a side note, what do you think REST PUT calls over HTTP on Node are?) Finagle is about composing async IO calls, e.g. here http://twitter.github.com/scala

(as a side note, what do you think REST PUT calls over HTTP on Node are?) Finagle is about composing async IO calls, e.g. here http://twitter.github.com/scala_school/finagle.html http://twitter.github.com/scala_school/finagle.html This works much better in Scala, as Java is not very good at composing Futures. It needs a lot of boiler plate code as it lacks noise free closures.
