I don't like slices in D

[Vitali]

I expected slices to be in D (http://dlang.org/arrays.html) like 
they are in Go 
(http://blog.golang.org/go-slices-usage-and-internals). But they 
are not.

Why the array have to be reallocated after the length of a slice 
is changed? It makes slices useless.

Here a little example (it fails):

  void testSlices() {
    int[] dArr = [10, 11, 12];
    int[] dSlice = dArr[0..2];
    dSlice.length++;
    assert(dArr[2]==dSlice[2]); // failure
  }
