This should be straightforward, at the risk of extra copying. Something
like:
static def copyTo[T](A:Array[T], p:Place):Array[T]{self.dist == A.region
->p} {
val ACopy = ValRail.make(0.. A.region.size()-1, (i:int) =>
A(A.region.coord(i)));
at (p)
return Array.make[T](A.region -> p, (p:Point) =>
ACopy(A.region.ord(p)));
}
