Type Equalities, Disequalities and obsoleting of Overlapping Instances
Type equality predicates: from OverlappingInstances to overcoming them Type equality predicates decide if two types are equal and return the result of the comparison as a type-level boolean. A type equality predicate ought to be total for ground types, that is, types with no free type variables. A more general type matching predicate compares the shape of two types, their top-level type constructo
Efficient and Insightful Generalization
How OCaml type checker works -- or what polymorphism and garbage collection have in common There is more to Hindley-Milner type inference than the Algorithm W. In 1988, Didier Rémy was looking to speed up the type inference in Caml and discovered an elegant method of type generalization. Not only it is fast, avoiding scanning the type environment. It smoothly extends to catching of locally-declare
