Dave suggested pointer equality only on mutable boxes, but deep equality
on immutable boxes. This might be a nice sweet spot.
Feels more POLS-violating to me than either shallow or deep+fail.
Or, um, marijn's suggestion might also be ok (if odd in a systems
language), about a fast path + slow path combo.
Switching by mutability feels particularly surprising.
