> {{AssignmentInformation}} is inefficient and creates lots of garbage that
> increase gc pressure. It creates 3 hashmaps that each contain only 2
> enum-based keys. This requires wrapper node objects, boxing/unboxing of ints,
> and more expensive lookups than simply using primitive arrays indexed by enum
> ordinal.
