Hindley-milner type
WebbThe type inference is based on the standard Hindley-Milner (HM) type inference algorithm, but extended in various way to accommodate subtyping, region inference, and higher-ranked types. A note on terminology We use the notation ?T to refer to inference variables, also called existential variables. WebbLecture 11: Type Inference In the last lecture, we designed a system for categorizing the expressions in our programs with types, and created an algorithm for checking whether …

Webb29 mars 2024 · Hindley–Milner in Python A Hindley–Milner type system allows a programming language's types to be inferred with few or no explicit type annotations. A unique property of Hindley–Milner type systems is that type constraints are propagated both forward and backward throughout a program. WebbA Hindley–Milner ( HM) type system is a classical type system for the lambda calculus with parametric polymorphism. It is also known as Damas–Milner or Damas–Hindley–Milner. It was first described by J. Roger Hindley [1] and later rediscovered by Robin Milner. [2]
