Quick and dirty version of Map in Scala that can be 'called' like Python dicts where unknown methods are pulled out as Map keys. Uses the 2.9 dynamic trait.

CallableMap.scala

class CallableMap extends scala.collection.mutable.HashMap[String, Any] with Dynamic {

  def invokeDynamic(name: String)(args: Any*) = {
    println("Invoke Dynamic: (name = %s)(args: %s)".format(name, args))
    get(name)
  }

  def typed[T]: T = {
    asInstanceOf[T]
  }
}

val data = new CallableMap

data put ("foo", "bar")
data put ("bar", "baz")
data put ("x", "y")

/* scala> data.foo
dynatype: line9$object.$iw.$iw.data.invokeDynamic("foo")()
Invoke Dynamic: (name = foo)(args: List())
res8: Option[Any] = Some(bar)

scala> data.bar
dynatype: line9$object.$iw.$iw.data.invokeDynamic("bar")()
Invoke Dynamic: (name = bar)(args: List())
res9: Option[Any] = Some(baz)

scala> data.baz
dynatype: line9$object.$iw.$iw.data.invokeDynamic("baz")()
Invoke Dynamic: (name = baz)(args: List())
res10: Option[Any] = None */

Hello, how can i import the Dynamic trait?
