Hindley-milner
Webb进行类型推论的常用算法是 Hindley–Milner 或 Damas–Milner 算法。 这个算法的起源是Haskell B. Curry和Robert Feys在1958年为简单类型lambda演算设计的类型推论算法。 在 1969 年Roger Hindley扩展了这项工作并证明他们的算法总能推出最一般的类型。 在 1978 年Robin Milner，独立于 Hindley 的工作，提供了等价的算法。 在 1985 年Luis … WebbSolución: Hindley-Milner es un sistema de tipos descubierto de forma independiente por Roger Hindley (que estaba mirando la lógica) y más tarde por Robin Milner (que estaba mirando los lenguajes de programación). Las ventajas de Hindley-Milner son. Es compatible polimórfico funciones; por ejemplo, una función que puede darle la longitud ...

AU - Lindley, Samuel. PY - 2008/6. Y1 - 2008/6. N2 - We implement statically-typed multi-holed contexts in OCaml using an underlying algebraic datatype augmented with phantom types. Existing approaches require dynamic checks or more complex type systems.

Webb26 mars 2024 · Hindley-Milner (HM) type inference contrasts with more restricted “local” approaches to type inference, found in languages like Scala and C#, which often require the types of variables to be annotated explicitly by programmers. Webb13 apr. 2024 · OCaml 非常的快，粗略地说，同样的代码规模下，使用 C++ 表达则可能需要加倍代码量和 3 倍编译时间。 ML（Meta Language）元语言是一个函数式、指令式的通用的编程语言，它著称于使用了多态的 Hindley–Milner 类型推论。
WebbIs this even possible to typecheck using a hindley-milner-ish type system without further annotations? If so, how does one go about determining that foo and bar are called/instantiated with A=string without some kind of flow/data-analysis? Would be great if someone could recommend me some entry-level blog/paper on compiling such things

Write. map (\ x -> x + 1) [1, 2] It's not clear why you want Either to be involved, since you're mapping over a list without any Either values in it. Maybe what you want is. map (\ (Left x) -> x + 1) [Left 1, Left 2] lp pla2 laborwertWebbIn type theory and functional programming, Hindley–Milner (HM), also known as Damas–Milner or Damas–Hindley–Milner, is a classical type system for… Expand Wikipedia Create Alert Papers overview Semantic Scholar uses AI to extract papers important to this topic. Review 2009 Dependently typed programming in Agda U. Norell lpplayer日本語版WebbThis paper describes a simple extension of the Hindley-Milner polymorphic type discipline to call-by-value languages that incorporate imperative features like references, exceptions, and continuations. This extension sacrifices the ability to type every purely functional expression that is typable in the Hindley-Milner system.

Milner [milner78] independently described a similar algorithm, which also introduced the notion of first-order polymorphism, often called let-polymorphism or ML style polymorphism. lp plus bayern gymnasium
