For reference, the discussion is here [1]. Szeder Gábor has a dissenting
argument in [2] that makes sense to me (gdb on my desktop also shows an
enum used as a bitset as "(A | B)"). But in any case, perhaps we should
decide if it's fine to use an enum here before Wambui Karuga continues
development.

Good point.
