I probably don't have a very relevant opinion here, but it would be
clearer to me to have direction be expressed in terms of msb/lsb
rather than left/right. In the end the shift input and result are
numbers, and while I don't know the bit endianness of numbers (and
AFAICT it's not relevant and neither exposed by the API), msb/lsb on
the other hand do make sense.
