Heh. Do you have *any idea* how long it took me to finish debugging this 
JavaScript snippet?

function Bindings_Lookup(key)
{
   if (this.Key  == key) return this.Value;
   this.Next.Lookup(key);
}

It took an absurd amount of time to figure this out - especially given 
the strange way Firefox responded to it...

Sure, they'll never make a programming language where mistakes are 
impossible. But mutable state just offers *so many* ways to shoot 
yourself in the foot. :-/
