Hmm, like demonstrated in HOP?<P>
But - out of curiosity - could you please elaborate "not very efficient"? Did you benchmark it? Or do you mean memory consumption?<P>
When brainstorming, possible alternatives come into mind to realize a second slot in perl5 (like dualvars, tieing, blessing, glob-slots,...). <P>

PS: I'm well aware of the pros of CONS... ;-)
