I suppose the following is not a bug, but confusing it is:
```
void main()
{
import std.stdio;
import std.bitmanip;
BitArray ba = [1, 1, 1, 1, 1, 1, 1, 1];
writeln(ba); // [1, 1, 1, 1, 1, 1, 1, 1]
ba >>= 4; // right shift
writeln(ba); // [1, 1, 1, 1, 0, 0, 0, 0] bits shifted left
}```
I suppose this is because the array is printed left-to-right,
whereas the bits in a byte are typically ordered right-to-left. I
suppose I should interpret the bits in the array to increase in
significance with increasing index (little endian) and that
right-shift means a shift towards less significance (which is to
the right in big endian).
The documentation of <<= and >>= [1] however just talks about
left and right, without defining left and right or clarifying
that the directions are reversed from how the array is printed.
Is there something I have missed?
