I am a newbie to `scala`. I try to write a function that is "repeating" an `Array` (Scala 2.9.0):

```
def repeat[V](original: Array[V],times:Int):Array[V]= {
if (times==0)
   Array[V]()
else
  Array.concat(original,repeat(original,times-1)
}

```

But I am not able to compile this (get an error about the `manifest`)...
