C has bitfield support inside structs: unsigned tagsapplied :8;
and replace 8 with whatever value you want Bitfields are a bad idea imo; code has to be changed pretty severely to handle a varying-sized bitfield. You'd have to either limit the number of tags a user can create or else do a lot of work to generalize the code.
