Lambda calculus in haskell

TīmeklisIn this chapter we see how the Haskell language features we introduced in previous chapters (from function application rules based on Lambda Calculus to Typeclasses) lead to highly flexible and refactorable code and powerful abstractions. Tim's code stuff. About Notes on Programming Paradigms TīmeklisPurity and lambda calculus were baked into the language from the start. Lazy evaluation largely obviates the need for macros. The Hindley-Milner type system underpinning Haskell 98 lets us write code without a single type annotation. It feels like Lisp, yet an efficient type inference algorithm means the compiler rejects badly typed …

TīmeklisA lambda calculus term consists of: Variables, which we can think of as leaf nodes holding strings. Applications, which we can think of as internal nodes. Lambda abstractions, which we can think of as a special kind of internal node whose left child must be a variable. (Or as a internal node labeled with a variable with exactly one child.) Tīmeklislambda calculus interpreter what: A small lambda calculus interpreter written in C++. It supports α-conversion and β-reduction, as well as precise tracing output of replacements and renames. how: The standard lambda calculus syntax is supported, eg: (λz. ( ( (λx. (λy.x)) z) ( (λx. (λy.x)) z)))
