How often would this be useful? If its rare and only nice to have I would doubt it would be added to python. I have written a lot of low level protocol and IOCTL calls that cannot think of a time this would have helped me. struct is often a mean to create blocks of binary data. Long strings of binary data would be a maintenance issue. What do all the bits mean?
