Using inout in a foreach loop through a BitArray has no effect: the bits in the
BitArray do not change when assigned to or otherwise modified.

Can be easily circumvented by using a for loop, but is still an annoyance.

import std.bitarray;

void main() {
        BitArray a;
        a.length = 5;
        foreach (inout bit b; a) {
                assert (b == 0);
                b = 1;
        }
        foreach (bit b; a)
                assert (b == 1); // FAILS, they're all 0
}
