Actually after thinking about it, a macro like Sebastian has
is probably better. Otherwise the interface will be confusing
unless we limit it to getting just one bit instead of the whole
bank. So I now suggest let's just keep it in Sebastian's driver,
then we can move it later as it's just a one line.
