Actor is not supported on .net framework ?

hi,
I just compile the pingpong example using scalac-net , but error occurs:

C:\Users\tony\scala\pingpong>scalac-net pingpong.scala
pingpong.scala:1: error: value actors is not a member of package scala
import scala.actors.Actor
             ^
pingpong.scala:2: error: value actors is not a member of package scala
import scala.actors.Actor._
             ^
pingpong.scala:16: error: value start is not a member of Ping
  ping.start
       ^
pingpong.scala:17: error: value start is not a member of Pong
  pong.start
       ^
pingpong.scala:18: error: value ! is not a member of Ping
  ping ! Start
       ^
5 errors found


Is there a feature list that supports .net in scala?
Many thanks!

The same problem with addressbook.scala, but this time is in-line xml feature .

C:\Users\tony\scala\address>scalac-net addressbook.scala
addressbook.scala:35: error: value xml is not a member of package scala
    <head>

addressbook.scala:53: error: value xml is not a member of package scala
    <html>
     ^
addressbook.scala:16: error: value xml is not a member of package scala
      <table cellpadding="2" cellspacing="0">

Scala Actors depend on a lot of fairly low-level Java code, so no, they are not currently available on .NET.

This is indicative of a more general problem: It is impossible to write correct concurrent code in Scala, because there is no defined memory model.

You can write Scala code which is correct for concurrency with respect to the current implementation on the JVM, but there's no guarantee that it will be correct on .NET or that it will continue to be correct on future implementations of Scala.
