I don't consider this a hack at all.  Hmm.  I suppose a full
discussion of what "hack" means is offtopic, but to me if it's
not a semantic misuse of some kind, and doesn't result in
code that relies on an implementation detail not specified or
promised, then it isn't a hack.  What you're looking at here
is just an option for an effective implementation.
