Absolutely. But I meant clashes in the nomenclature: If we'd like to add a
'Count' title to pacman -[S|Q]i, we would have to rename '#define TITLE_COUNT'
to something else and adapt the code accordingly. No big deal, but I think it is
good practice to keep separate nomenclatures for the different families of

Another solution would be to prefix the enum with TITLE_ and the configuration
variables with TITLECFG_ for instance.
