.dup allocates a copy. The right implementation would be to copy 
the data yourself, then reduce length, and then just leave it at 
that.

void removeElement(ref int[] arr, int index) {
     for(size_t idx = index; idx < arr.length - 1; idx++)
         arr[idx] = arr[idx + 1];
     arr.length = arr.length - 1; // arr.length-- won't compile 
due to silliness
}
