UnrolledList range value type

[burner]

unittest
{
    UnrolledList!int list;
    list.insert(0);
    list.insert(0);
    list.insert(0);
    list.insert(0);
    list.insert(0);

    foreach(ref it; list.range) {
        it = 1;
    }

    foreach(it; list.range) {
        assert(it == 1);
    }
}

I think UnrolledList!int.Range.front needs to return ref int . But ref is sort of f*** up so I can't simple cast to ref int. @Hackerpilot ideas?

p.s. This only affects value types.
p.s.s HashMap is also affected
