  Provides scala API for 'go-like' CSP channels.

  Provides scala API for 'go-like' CSP channels.

  Overview

  see readme for quick introduction.

  Usage

  At first you must receive gopherApi as Akka extension:

  import gopher._
  
  .....
  val gopherApi = Gopher(actorSystem)

  Then you can use CPS channels with blocling operations inside go clauses:

  val channel = gopherApi.makeChannel[Long]
  val n = 10000
  val producer = go {
   @volatile var(x,y) = (0L,1L)
   for( s <- gopherApi.select.forever) {
     case z: channel.write if (z==x) =>
                x = y
                y = x+z
                if (x > n) {
                   channel.close
                   implicitly[FlowTermination[Unit]].doExit()
                }
   }
  }
  val consumer = for((c,i) <- channel.zip(1 to n)) {
     Console.println(s"fib(${i})=${c}")
  }
  Await.ready(consumer, 10 seconds)

  and defer/recover in go/goScope

  goScope{
    val f = openFile(myFileName)
    defer{
      if (! recover{case ex:FileNotFoundException => Console.println("invalid fname")}) {
         f.close()
      }
    }
  }
