would one want to use the occasion to get rid of the bazillion variables mapped to a struct array and have atom(Atom a) and atomString(Atom a) for an array of atoms a matching string - maybe including some namespaces so that instead of p->atom->net_wm_to_many_underscores one would have atom(NET::WM::NoUnderscores) and atom(WM::NoUnderscores) etc.?
Ideally with a little preprocessor and include magic?
