Modeling Class Hierarchies with Contradictions
Summary: Proposes a language feature to permit contradictory class definitions in object hierarchies, acknowledging overlap. Defines a semantics that separates class from type and preserves subset/subtype relations, enabling type-error detection and reducing runtime checks in queries.
