The binary lists offer internal operations on a bit level, using the C. operations. However at the moment there is no function interpreting integers as bit lists or vice versa. nevertheless, as long as you want the bits only to store properties, binary lists should do the job.

Offering such operations for integers is somewhat problematic, because there are already different internal storages (depending on whether the integer is small or large) with further representations in the wings. I don't know whether any such representation is guaranteed to always be consistent with bitwise operations.

All the best,
