I'm afraid := isn't the fully fledged unification operator you're hoping for. As I'll explain in Exegesis 3, it's really just an aliasing mechanism.

So your declarative emergent $x and $y values aren't actually being declared, or emerging either. :-(

In fact, you'd just get $x aliased to the (constant) result of $y+5 (which will be 5 if there's no prior assignment to $y), and then $y aliased to the (constant) result of $x-3 (which will be 2 under the previous assumption).

However, as a consolation prize for having suggested human sacrifice to me (you did intend it to be a human burnt offering, didn't you???), I have now added a Data::Unification module to my ToDo list. ;-)
