And this is probably one of several reasons that Damian Conway places Quantum::Superpositions in the "Damian modules you shouldn't use in production because their purpose is to explore and prototype future core language features" category in his Categorized Damian Modules list.
The performance sucks, but, at least according to TheDamian, it was never intended to be used in production.
