 // IMPLEMENTATION
 //
 // Internally, all 'primitive' types, and their unions, are represented as
 // bitsets. Class is a heap pointer to the respective map. Only Constant's, or
 // unions containing Class'es or Constant's, currently require allocation.
 // Note that the bitset representation is closed under both Union and Intersect.
 //
 // There are two type representations, using different allocation:
