Nice work!
If I have a matrix like

1 2
3 4

iota(4).sliced(2,2);

Is there a way to transform it to:

1 1 1 2 2 2
1 1 1 2 2 2
1 1 1 2 2 2
3 3 3 4 4 4
3 3 3 4 4 4
3 3 3 4 4 4

or

0 0 0 0 0 0
0 1 0 0 2 0
0 0 0 0 0 0
0 0 0 0 0 0
0 3 0 0 4 0
0 0 0 0 0 0

?

Of course the inverse operation seems quite easier to do using slices.

```
import std.algorithm, std.range, std.stdio;
auto m = iota(1, 5).sliced(2, 2);
"%(%(%s %)\n%)\n".writefln(m);

auto w = createSlice!int(6, 6);

w[1..$, 1..$].strided!0(3).strided!1(3)[] = m;
"%(%(%s %)\n%)\n".writefln(w);

foreach(i; 0..3)
    foreach(j; 0..3)
        w[i..$, j..$].strided!0(3).strided!1(3)[] = m;
"%(%(%s %)\n%)\n".writefln(w);
```

Prints:

1 2
3 4

0 0 0 0 0 0
0 1 0 0 2 0
0 0 0 0 0 0
0 0 0 0 0 0
0 3 0 0 4 0
0 0 0 0 0 0

1 1 1 2 2 2
1 1 1 2 2 2
1 1 1 2 2 2
3 3 3 4 4 4
3 3 3 4 4 4
3 3 3 4 4 4

What does the job entail?

I volunteer then, if you'll have me.

Another way:
w[1..2, 1..2] = m;
