My attempt to rewrite the switch (failed : )

ddata\ddata.d(94): Error: slice expression array[] is not a modifiable 
lvalue
ddata\ddata.d(169): template instance ddata.ddata.setLength!(int[]) error 
instantiating

//an array depth walker  :)
void setLength (T)( ref T array, int depth , int index)
{
 if(depth > 0)
 {
  depth--;
  setLength (array[], depth, index); //94
 }
 else
 {
  if(array.length < index) array.length = array.length * 2;
 }
}
