For example, when extending the definition of an abstract variable to include abstract records, operations upon a field F of a record variable R, clearly involve F, which is distinct from, but also a part of, R. A partial aliasing axiom would state that changing a field of one record variable does not affect any other records.
The result is a type or value, depending on which sort of generic definition is applied. Generic abstraction enables generic definitions be defined by abstracting a type parameter (of a given kind). Type-indexed types are types that are indexed over the type constructors. These can be used to give types to more involved generic values.
