Currently, instead of setting the length to zero, you should start with 
the whole slice.

Instead, you can use the output range primitive put().

When slice.empty, it would have covered the static array completely:

import std.range;

void foo()
{
    int[2] buffer;
    int[] slice = buffer[];

    foreach (int i, _; slice) {
        slice.put(i);
    }

    assert(buffer == [ 0, 1 ]);
}

void main()
{
    foo();
}
