          Issue ID: 13610
           Summary: bringToFront does not work with CTFE
           Product: D
           Version: D2
          Hardware: x86_64

bringToFront does not work with CTFE. I don't know whether it is supposed to
but
it certainly is surprising.

import std.algorithm : bringToFront;
// at running time
{
    auto array = [1, 2, 3, 4];
    bringToFront(array[0 .. $-1], array[$-1 .. $]);
    assert(array == [4, 1, 2, 3]);
}
// at compile time
{
    enum array = [1, 2, 3, 4];
    bringToFront(array[0 .. $-1], array[$-1 .. $]);
    static assert(array == [4, 1, 2, 3]); // fails
}

says
Error: static assert  ([1, 2, 3, 4] == [4, 1, 2, 3]) is false

I used dmd v2.066.0 on Linux.
